Subject: drivers/video: fsl-diu-fb: remove unused ioctls
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=4a64e49df282d55754f9bbb5f14ca4d783128df4;p=mv-sheeva.git

drivers/video: fsl-diu-fb: remove unused ioctls

Remove some unused ioctl commands, and treat those commands as unsupported
instead of ignored.

Also remove struct mfb_alpha, which isn't used by any ioctl.  It may have
been once intended for MFB_SET_ALPHA, but that ioctl uses a different
data structure.
