-Subject: [PATCH] staging: bcm2835-audio: Drop debug messages in
- bcm2835-pcm.c
-
-commit 055e1c330d04df87d4730a5db837161c11ddaafc upstream.
-
-These debug messages worsen the code readability a lot while they give
-little debuggability (which we already have via tracing, in anyway).
-
-Let's clean them up.  This allows us to reduce the
-snd_bcm2835_pcm_lib_ioctl() function to be a direct call of the
-snd_pcm_lib_ioctl callback (like most other drivers do), too.
