Subject: [PATCH] fbdev: Minor cleanup in WM8505-related code

This fixes vsync timing calculation in wm8505fb.c (was off by one,
which caused some flicker with larger panels) and replaces the last
remaining driver name reference with the macro for uniformity.

In addition, the error return path in wmt_ge_rops.c is made more
uniform by getting rid of goto's in remaining places.

Paul, could you please apply this to your fbdev tree? The patch seems
to be trivial, and it would bring the mainline code in line with what
people use when pulling from our Gitorious development repo.

Best regards,
Alexey
