Subject: ALSA: seq: Drop superfluous error/debug messages after malloc failures
X-Git-Tag: v3.16.35~363
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=004fb6ebf10a0bd4ce17ffab124531038e3974d6;p=thirdparty%2Fkernel%2Fstable.git

ALSA: seq: Drop superfluous error/debug messages after malloc failures

commit 24db8bbaa3fcfaf0c2faccbff5864b58088ac1f6 upstream.

The kernel memory allocators already report the errors when the
requested allocation fails, thus we don't need to warn it again in
each caller side.
