[alsa-devel] [PATCH] dbri: driver cleanup
Krzysztof Helt
krzysztof.h1 at wp.pl
Sat Aug 18 08:27:30 CEST 2007
From: Krzysztof Helt <krzysztof.h1 at wp.pl>
This patch fixes white spaces, spelling and formatting
to conform closer to the coding standard of the kernel.
It contains few fixes pointed out by the checkpatch.pl script.
Signed-off-by: Krzysztof Helt <krzysztof.h1 at wp.pl>
