From 0ea617a298dcdc2251b4e10f83ac3f3e627b66e3 Mon Sep 17 00:00:00 2001 From: Colin Ian King Date: Thu, 8 Dec 2016 13:05:43 +0000 Subject: ASoC: rsnd: don't double free kctrl 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.
