Otherwise we'd still end up w/ the plane attached to the CRTC, and
seemingly active, but without an FB. Which ends up going *boom*
in the drivers.
Slightly modified version of Daniel's irc suggestion.
Note that the big problem isn't drivers going *boom* here (since we
already have the situation of planes being left enabled when the crtc
goes down). The real issue is that the core assumes the primary plane
always goes down when calling ->set_config with a NULL mode. Ignoring
that assumption leads to the legacy state pointers plane->fb/crtc
getting out of sync with atomic, and that then leads to the subsequent
*boom* all over the place.

So the problem with async commit (especially async modeset commit) is
that the legacy pointers only get updated after the point of no
return, in the async part of the modeset sequence. At least as
implemented by the current helper functions. This is done in the
set_routing_links function in drm_atomic_helper.c.
Which also means that access isn't protected by locks but only
coordinated by synchronizing with async workers. No problem thus far,
until we lock at the getconnector/encoder ioctls.
So fix this up by adding special cases for atomic drivers: For those
we need to look at state objects. Unfortunately digging out the
correct encoder->crtc link is a bit of work, so wrap this up in a
helper function.
Moving the assignments of connector->encoder and encoder->crtc earlier
isn't a good idea because the point of the atomic helpers is that we
stage the state updates. That way the disable functions can still
inspect the links and rely upon them.
v2: Extract full encoder->crtc lookup into helper (Rob).
v3: Extract drm_connector_get_encoder too since - we need to always
return state->best_encoder when there is a state otherwise we might
return stale data if there's a pending async disable (and chase
unlocked pointers, too). Same issue with encoder_get_crtc but there
it's a bit more tricky to handle.

Chasing plane->state->crtc of planes that are *not* part of the same
atomic update is racy, making it incredibly awkward (or impossible) to
do something simple like iterate over all planes and figure out which
ones are attached to a crtc.
Solve this by adding a bitmask of currently attached planes in the
crtc-state.
Note that the transitional helpers do not maintain the plane_mask. But
they only support the legacy ioctls, which have sufficient brute-force
locking around plane updates that they can continue to loop over all
planes to see what is attached to a crtc the old way.
Signed-off-by: Rob Clark <robdclark@gmail.com>
[danvet:
- Drop comments about locking in set_crtc_for_plane since they're a
bit misleading - we already should hold lock for the current crtc.
- Also WARN_ON if get_state on the old crtc fails since that should
have been done already.
- Squash in fixup to check get_plane_state return value, reported by
Dan Carpenter and acked by Rob Clark.]

In commit fadbe0cd5292851608e2e01b91d9295fa287b9fe entitled "staging:
rtl8188eu:Remove rtw_zmalloc(), wrapper for kzalloc()", the author failed
to note that the original code in the wrapper tested whether the caller
could sleep, and set the flags argument to kzalloc() appropriately.
After the patch, GFP_KERNEL is used unconditionally. Unfortunately, several
of the routines may be entered from an interrupt routine and generate
a BUG splat for every such call. Routine rtw_sitesurvey_cmd() is used in the

Jonathan writes:
Third set of IIO fixes for the 3.18 cycle.
Most of these are fairly standard little fixes, a bmc150 and bmg160 patch
is to make an ABI change to indicated a specific axis in an event rather
than the generic option in the original drivers. As both of these drivers
are new in this cycle it would be ideal to push this minor change through
even though it isn't strictly a fix. A couple of other 'fixes' change
defaults for some settings on these new drivers to more intuitive calues.
Looks like some useful feedback has been coming in for this driver
since it was applied.
* IIO_EVENT_CODE_EXTRACT_DIR bit mask was wrong and has been for a while
0xCF clearly doesn't give a contiguous bitmask.
* kxcjk-1013 range setting was failing to mask out the previous value
in the register and hence was 'enable only'.
* men_z188 device id table wasn't null terminated.
* bmg160 and bmc150 both failed to correctly handling an error in mode
setting.
* bmg160 and bmc150 both had a bug in setting the event direction in the
event spec (leads to an attribute name being incorrect)
* bmg160 defaulted to an open drain output for the interrupt - as a default
this obviously only works with some interrupt chips - hence change the
default to push-pull (note this is a new driver so we aren't going to
cause any regressions with this change).
* bmc150 had an unintuitive default for the rate of change (motion detector)
so change it to 0 (new driver so change of default won't cause any
regressions).

This patch adds a driver for the Analog Devices adv7511. The adv7511 is
a standalone HDMI transmitter chip. It features a HDMI output interface
on one end and video and audio input interfaces on the other.

The drm_get_edid() function performs direct I2C accesses to read EDID
blocks, assuming that the monitor DDC interface is directly connected to
the I2C bus. It can't thus be used with HDMI encoders that control the
DDC bus and expose EDID blocks through a different interface.
Refactor drm_do_get_edid() to take a block read callback function
instead of an I2C adapter, and export it for direct use by drivers.
As in the general case the DDC bus is accessible by the kernel at the
I2C level, drivers must make all reasonable efforts to expose it as an
I2C adapter and use drm_get_edid() instead of abusing this function.

DRM slave encoders require their associated struct drm_encoder instance
to be embedded in a struct drm_slave_encoder. This makes processing
encoders regardless of their types needlessly and painfully complex in
drivers that use a mix of slave encoders and custom encoders. Such a
driver will need to either create drm_slave_encoder instances that fake
their embedded encoder instance, or to turn all drm_encoder instances
into drm_slave_encoder instances.
Between the two evils, one must choose the lesser. Use drm_slave_encoder
everywhere.

Some VF drivers use the upper byte of "param1" (the qp count field)
in mlx4_qp_reserve_range() to pass flags which are used to optimize
the range allocation.
Under the current code, if any of these flags are set, the 32-bit
count field yields a count greater than 2^24, which is out of range,
and this VF fails.
As these flags represent a "best-effort" allocation hint anyway, they may
safely be ignored. Therefore, the PF driver may simply mask out the bits.

Currently we just make sure vdd is off before suspending, but we don't
cancel the vdd off work. The work wil not touch vdd if
want_panel_vdd==false so in theory this is fine.
In the past that was perfectly fine since the vdd off work didn't do
anything when want_panel_vdd==false, so even if the work would have been
run during system resume before i915 has resumed, nothing would happen.
However since pps_lock() will now grab the power domain references before
it can check want_panel_vdd, we may end up toggling the power wells on/off
already before the driver has resumed. That is not really acceptable, so
cancel the vdd off work when suspending the encoder.
The problem appeared when pps_lock() was introduced in:

If no voltage supply regulators are defined for the UFS devices (assumed
they are always-on), ufshcd_config_vreg_load() can be called on
suspend/resume paths with vreg == NULL as hba->vreg_info.vcc* equal to
NULL, and it causes NULL pointer dereference.
This fixes it by making ufshcd_config_vreg_{h,l}pm noop when no regulators
are defined.

When dynamic clk gating feature is enabled, delayed workqueue machanism
is used in order to detect certain period of inactivity. But there is no
guarantee that scheduled gating work is completed before module unloading.
So it can cause kernel crash by accessing memory after it was freed.
Fix it by cancelling clk gating and ungating works and ensure that its
execution is finished before module unloading.

Pull powerpc fixes from Ben Herrenschmidt:
"This series fix a nasty issue with radeon adapters on powerpc servers,
it's all CC'ed stable and has the relevant maintainers ack's/reviews.
Basically, some (radeon) adapters have issues with MSI addresses above
1T (only support 40-bits). We had powerpc specific quirk but it only
listed a specific revision of an adapter that we shipped with our
machines and didn't properly handle the audio function which some
distros enable nowadays.
So we made the quirk generic and fixed both the graphic and audio
drivers properly to use it.
Without that, ppc64 server machines will crash at boot with a radeon
adapter.
Note: This has been brewing for a while, it just needed a last respin
which got delayed due to us moving ozlabs to a new location in town
and other such things taking priority"
