From b522e61fb6329b68e6da8f237f21fc83a1d8ace2 Mon Sep 17 00:00:00 2001 From: Christian Gromm Date: Tue, 22 Dec 2015 10:52:58 +0100 Subject: [PATCH] staging: most: remove code to destroy channel This patch removes unnecessary code to destroy channel objects. It is needed, because function most_stop_channel, which is indirectly triggered by function most_deregister_interface, already destroys the channels.
