From 74b35a74f80e02bdd69db9cf96d3f4fe78b67064 Mon Sep 17 00:00:00 2001 From: Srinivas Kandagatla Date: Wed, 3 Jul 2019 13:30:02 +0100 Subject: [PATCH] ASoC: core: Return -ENOTSUPP from set_channel_map() if no operation provided It makes it easier for common code to work with snd_soc_dai_set_channel_map() by distinguishing between operation not being supported and an error. This is done inline with others snd_soc_dai.* apis.
