From a86308fc534edeceaf64670c691e17485436a4f4 Mon Sep 17 00:00:00 2001 From: Christophe JAILLET Date: Fri, 8 May 2020 05:56:03 +0300 Subject: [PATCH] wcn36xx: Fix error handling path in 'wcn36xx_probe()' In case of error, 'qcom_wcnss_open_channel()' must be undone by a call to 'rpmsg_destroy_ept()', as already done in the remove function.
