Subject: drm/omap: remove align_pitch()
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=6a5228fdf0a4636fdf5ce616c35264e0c0b26c7c;p=linux-beck.git

drm/omap: remove align_pitch()

The previous commit removed aligning the pitch to SGX's pitch
requirement from align_pitch(). What's left is effectively a function
that returns width * bytespp.

To clean up the driver, we can remove the function and have the
calculation inline in the two places which call align_pitch().
