Subject: Re: [PATCH] drivers/video/ep93xx-fb.c: clean up error-handling code

There were two problems in this code: failure of the setup function should
free locally allocated resources like other nearby failures, and the test
if (&info->cmap) can never be false. To generally clean things up, this
patch reorders the error handling code at the failed label and adds labels
so that the conditionals are not necessary.

Oddly, scripts/get_maintainer.pl on this file doesn't return me, even
though, according to git blame, I am the author of 90% of the commits.
Should I have an entry in the MAINTAINERS file, or is
scripts/get_maintainer.pl not working properly?
There are optional differences in using scripts/get_maintainer.pl.
If you use './' ahead of file path, you will see your name.
Without './' ahead of 'drivers/video/ep93xx-fb.c':
./scripts/get_maintainer.pl --file drivers/video/ep93xx-fb.c
