[Nishanth Menon]

Some basic cleanups for kernel-doc errors or missing documentation
parameters.

It does seem the drm_edid.c could do with some amount of documentation cleanup,
but I have stayed with the bare minimum.
the above error is based off:
master de1a226 Merge tag 'writeback-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/wfg/linux
from: git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux-2.6.git

defconfig used: omap2plus_defconfig

Disclaimer: I am no drm expert, and I tried to use my best judgement about what
the meaning of the parameters might be, hope it helps.
