4.4-stable review patch. If anyone has any objections, please let me know.
------------------ From: Colin Ian King <[email protected]> [ 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.
