Subject: [PATCH 1/2] ALSA: cmipci: Allocate with GFP_KERNEL instead of GFP_ATOMIC
Date: Mon, 16 Apr 2018 14:12:05 +0200	[thread overview]
Message-ID: <20180416121206.27131-2-tiwai@suse.de> (raw)
In-Reply-To: <20180416121206.27131-1-tiwai@suse.de>

save_mixer_state() is called in a sleepable context, so it's safe to
allocate with GFP_KERNEL instead of the current GFP_ATOMIC.  The
GFP_ATOMIC usage must have been based on an incorrect assumption in
the very old code base.
