Subject: [PATCH 04/14] ASoC: compress: Fix memory leak from snd_soc_new_compress
Date: Wed,  5 Jun 2019 15:45:46 +0200	[thread overview]
Message-ID: <20190605134556.10322-5-amadeuszx.slawinski@linux.intel.com> (raw)
In-Reply-To: <20190605134556.10322-1-amadeuszx.slawinski@linux.intel.com>

Change kzalloc to devm_kzalloc, so compr gets automatically freed when
it's no longer needed.
