Also cleaned up some checks before calls to kfree(). kfree(NULL) is OK.

In v3.3, the gma500 drm driver moved from staging to drm group by
Alan Cox's 3abcf41f patch. the gma500 drm driver should control
brightness well and don't need gma500 stub driver anymore.

DP link training is now handled as part of the supervisor processing,
and can no longer race with it.
Signed-off-by: NBen Skeggs <bskeggs@redhat.com>

We need to be able to do link training for PIOR-connected ANX9805 from
the third supervisor handler (due to script ordering in the bios, can't
have the "user" call train because some settings are overwritten from
the modesetting bios scripts).

This moves link training for SOR-connected DP encoders to the second
supervisor interrupt, *before* we call the modesetting scripts (yes,
different ordering from PIOR is necessary).  This is useful since we
should now be able to remove some hacks to workaround races between
the supervisor and link training paths.

A single U encoder table can match multiple DCB entries, whereas the

For off-chip transmitters we won't necessarily have an i2c table entry
to lookup, but we can do it instead by encoding the type to include
the extdev type and looking that up instead.

This is about to become somewhat more complicated to determine in a

the encoder structure.
