This is some janitorial updates to the via driver
that is required to get rid of deprecated headers
in the drm subsystem.
The first three patches are trivial, where
the dependencies on drmP.h and drm_os_linux are dropped.
The remaining three patches drop use of DRM_WAIT_ON().
They are replaced by wait_event_interruptible_timeout().
These patches could use a more critical review.
When replacing DRM_WAIT_ON() I took care to not change the uapi,
by continue to use the original return codes.
The following table was used for the transition:
DRM_WAIT_ON wait_event_interruptible_timeout
----------- ---------------------------------
condition OK: ret >= 1
timeout: -EBUSY 0
interrupted: -EINTR -ERESTARTSYS
The changes has been build tested only.
Testing on a real device would be highly appreciated.
I had preferred that the via driver was replaced by the
openchrome driver, but until we have it then we need
to deal with the legacy via driver to remove old cruft
in the drm subsystem.
Note: A simpler approach had been to copy DRM_WAIT_ON
to via_drv.h, but then the actual solution is
presumeably better.
