I believe this is a typo.

This sets the fbcon to use TRUECOLOR by default, it then
only modifies the pseudo palette for fbcon, and only touches
the real palette when in 8-bit pseudo color mode.

The previous patches had some unwanted side effects, I've fixed
the lack of 32bpp working, and fixed up 16bpp so it should also work.
this also adds the interface to allow the driver to set a preferred
console depth so for example low memory rn50 can set it to 8bpp.
It also catches 24bpp on cards that can't do it and forces 32bpp.
Tested on r100/r600/i945.

This adds support for the setcmap api and fixes the 8bpp
support at least on radeon hardware. It adds a new load_lut
hook which can be called once the color map is setup.

Compiling DRM throws the following warning if MAGIC_SYSRQ is disabled:
drivers/gpu/drm/drm_fb_helper.c:101: warning: 'sysrq_drm_fb_helper_restore_op' defined but not used
Fix: place sysrq_drm_fb_helper_restore_op and associated
definitions inside #ifdef CONFIG_MAGIC_SYSRQ.

This initialises the fb helper with the connector helper,
so that the fb cmdline code works for intel as well.

If drivers don't init the fb helper on the connector, the cmdline
code won't work, but it shouldn't crash either.

[note this requires an fb patch posted to linux-fbdev-devel already]
This uses the normal video= command line option to control the kms
output setup at boot time. It is used to override the autodetection
done by kms.
video= normally takes a framebuffer as the first parameter, in kms
it will take a connector name, DVI-I-1, or LVDS-1 etc. If no output
connector is specified the mode string will apply to all connectors.
The mode specification used will match down the probed modes, and if
no mode is found it will add a CVT mode that matches.
video=1024x768 - all connectors match a 1024x768 mode or add a CVT on
video=VGA-1:1024x768, VGA-1 connector gets mode only.
The same strings as used in current fb modedb.c are used, except I've
added three more letters, e, D, d, e = enable, D = enable Digital,
d = disable, which allow a connector to be forced into a certain state.

The drm_fb_helper shouldn't mess with CRTCs that aren't enabled or in
its initial config. Ideally it shouldn't even include CRTCs in its
initial config if they're not in use, but my old fix for that no longer
works. At any rate, this fixes a real bug I was seeing where after a
console blank, both pipes would come back on, even though only one had
been enabled before that. Since the other pipe had a bogus config,
this led to some screen corruption.

Allow the KMS module to work properly, and also rename
it to KMS_HELPER so its clearer what its for.

Set accel to none, we really don't want anyone thinking
fb is an accel interface.
Pass pitch not depth to function for intel.

Initially I always meant this code to be shared, but things
ran away from me before I got to it.
This refactors the i915 and radeon kms fbdev interaction layers
out into generic helpers + driver specific pieces.
It moves all the panic/sysrq enhancements to the core file,
and stores a linked list of kernel fbs. This could possibly be
improved to only store the fb which has fbcon on it for panics
etc.
radeon retains some specific codes used for a big endian
workaround.
changes:
fix oops in v1
fix freeing path for crtc_info
