Date: Wed, 15 Nov 2017 02:45:46 +0000 From: alexander.levin@...izon.com To: "linux-kernel@...r.kernel.org" <linux-kernel@...r.kernel.org>, "stable@...r.kernel.org" <stable@...r.kernel.org> Cc: Colin Ian King <colin.king@...onical.com>, Mark Brown <broonie@...nel.org>, alexander.levin@...izon.com Subject: [PATCH AUTOSEL for 4.9 47/56] ASoC: rsnd: don't double free kctrl From: Colin Ian King <colin.king@...onical.com> [ Upstream commit 0ea617a298dcdc2251b4e10f83ac3f3e627b66e3 ] On an error, snd_ctl_add already free's kctrl, so calling snd_ctl_free_one to free it again leads to a double free error. Fix this by removing the extraneous snd_ctl_free_one call.
