irqchip/gicv3-its: Add workaround for QDF2400 ITS erratum 0065

2017-03-22T11:43:39+00:00

commit 90922a2d03d84de36bf8a9979d62580102f31a92 upstream.

On Qualcomm Datacenter Technologies QDF2400 SoCs, the ITS hardware
implementation uses 16Bytes for Interrupt Translation Entry (ITE),
but reports an incorrect value of 8Bytes in GITS_TYPER.ITTE_size.

It might cause kernel memory corruption depending on the number
of MSI(x) that are configured and the amount of memory that has
been allocated for ITEs in its_create_device().

This patch fixes the potential memory corruption by setting the
correct ITE size to 16Bytes.

drm/vc4: Fix ->clock_select setting for the VEC encoder

2017-03-22T11:43:39+00:00

commit ab8df60e3a3b68420d0d4477c5f07c00fbfb078b upstream.

PV_CONTROL_CLK_SELECT_VEC is actually 2 and not 0. Fix the definition and
rework the vc4_set_crtc_possible_masks() to cover the full range of the
PV_CONTROL_CLK_SELECT field.

drm/vc4: Fix race between page flip completion event and clean-up

2017-03-22T11:43:39+00:00

commit 26fc78f6fef39b9d7a15def5e7e9826ff68303f4 upstream.

There was a small window where a userspace program could submit
a pageflip after receiving a pageflip completion event yet still
receive EBUSY.

usb: gadget: udc: atmel: remove memory leak

2017-03-22T11:43:39+00:00

[ Upstream commit 32856eea7bf75dfb99b955ada6e147f553a11366 ]

Commit bbe097f092b0 ("usb: gadget: udc: atmel: fix endpoint name")
introduced a memory leak when unbinding the driver. The endpoint names
would not be freed. Solve that by including the name as a string in struct
usba_ep so it is freed when the endpoint is.

serial: 8250_pci: Detach low-level driver during PCI error recovery

2017-03-22T11:43:39+00:00

[ Upstream commit f209fa03fc9d131b3108c2e4936181eabab87416 ]

During a PCI error recovery, like the ones provoked by EEH in the ppc64
platform, all IO to the device must be blocked while the recovery is
completed.  Current 8250_pci implementation only suspends the port
instead of detaching it, which doesn't prevent incoming accesses like
TIOCMGET and TIOCMSET calls from reaching the device.  Those end up
racing with the EEH recovery, crashing it.  Similar races were also
observed when opening the device and when shutting it down during
recovery.

This patch implements a more robust IO blockage for the 8250_pci
recovery by unregistering the port at the beginning of the procedure and
re-adding it afterwards.  Since the port is detached from the uart
layer, we can be sure that no request will make through to the device
during recovery.  This is similar to the solution used by the JSM serial
driver.

I thank Peter Hurley  for valuable input on
this one over one year ago.

ACPI / blacklist: Make Dell Latitude 3350 ethernet work

2017-03-22T11:43:38+00:00

[ Upstream commit 708f5dcc21ae9b35f395865fc154b0105baf4de4 ]

The Dell Latitude 3350's ethernet card attempts to use a reserved
IRQ (18), resulting in ACPI being unable to enable the ethernet.

Adding it to acpi_rev_dmi_table[] helps to work around this problem.

Precision 5520 and 3520 either hang at login and during suspend or reboot.

It turns out that that adding them to acpi_rev_dmi_table[] helps to work

uvcvideo: uvc_scan_fallback() for webcams with broken chain

2017-03-22T11:43:38+00:00

[ Upstream commit e950267ab802c8558f1100eafd4087fd039ad634 ]

Some devices have invalid baSourceID references, causing uvc_scan_chain()
to fail, but if we just take the entities we can find and put them
together in the most sensible chain we can think of, turns out they do
work anyway. Note: This heuristic assumes there is a single chain.

At the time of writing, devices known to have such a broken chain are
  - Acer Integrated Camera (5986:055a)
  - Realtek rtl157a7 (0bda:57a7)
