Subject: ALSA: seq: Degrade the error message for too many opens
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=da10816e3d923565b470fec78a674baba794ed33;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

ALSA: seq: Degrade the error message for too many opens

ALSA OSS sequencer spews a kernel error message ("ALSA: seq_oss: too
many applications") when user-space tries to open more than the
limit.  This means that it can easily fill the log buffer.

Since it's merely a normal error, it's safe to suppress it via
pr_debug() instead.
