Pull drm update from Dave Airlie:
"Exynos and Radeon mostly, with a dma-buf and ttm fix thrown in.
It's a bit big but its mostly exynos license fix ups and I'd rather
not hold those up since its legally stuff.
Radeon has a couple of fixes from dma engine work, TTM is just a
locking fix, and dma-buf fix has been hanging around and I finally got
a chance to review it."
* 'drm-fixes' of git://people.freedesktop.org/~airlied/linux: (30 commits)

devm_request_and_ioremap API checks for NULL. Hence explicit
NULL check is not necessary. Saves some code.

devm_* APIs are device managed and get freed automatically when the
device detaches. Thus explicit freeing is not needed. This saves some
code.

This patch removes needless parenthesis.
This was pointed out but in case of fimc side. we missed it.

This patch fixes incorrect interrupt induced by m2m operation.
the m2m operation calls s/w reset every frame but there is the case that
the interrupt to m2m operation occures after s/w reset sometimes.
So this patch makes dma and capture operations stop at s/w reset
to avoid incorrect interrupt.

This patch removes color bar pattern register because we don't use the register anymore.
because it doesn't support color bar feature for writeback operation.
camera driver only supports color bar feature. but IPP doesn't support camera driver.

This patch considers both case of vflip and hflip.
If we want that the contents in buffer to be rotated to 180 degree,
then we can use h,vflip or 180 degree.
Changelog v2:
- added EXYNOS_DRM_FLIP_BOTH enum value to avoid build warnning.

This patch change current command name from cmd to c_node.
because we are using the member name, 'cmd', for command control ioctl in another structure.
so, this patch changes it to c_node to avoid such confusing.

CONFIG_HOTPLUG is going away as an option. As a result, the __dev*
markings need to be removed.
This change removes the use of __devinit, __devexit_p, and __devexit
from these drivers.
Based on patches originally written by Bill Pemberton, but redone by me
in order to handle some of the coding style issues better, by hand.

FIMC is stand for Fully Interfactive Mobile Camera and
supports image scaler/rotator/crop/flip/csc and input/output DMA operations
and also supports writeback and display output operations.
This driver is registered to IPP subsystem framework to be used by user side
and user can control the FIMC hardware through some interfaces of IPP subsystem
framework.
Changelog v6:
- fix build warning.
Changelog v1 ~ v5:
- add comments, code fixups and cleanups.
