Subject: [PATCH 1/2] fbdev: Minor cleanup in WM8505-related code

This replaces the last remaining driver name reference with the
macro for uniformity in wm8505fb.

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

Signed-off-by: Alexey Charkov <alchark@...il.com>

Splitted the vsync change (will follow in PATCH 2/2) from trivial
cleanups. This indeed makes sense for at least bisecting purposes.
Thanks Mayuresh for the suggestion!

Best regards,
Alexey
