[alsa-devel] [PATCH] sound/pci/azt3328.c: adjust error handling code to include debugging code

Julia Lawall julia at diku.dk
Wed Aug 10 11:49:04 CEST 2011


From: Julia Lawall <julia at diku.dk>

snd_azf3328_dbgcallenter is called at the very beginning of the function,
so it could be useful to call snd_azf3328_dbgcallleave at all exit points.
