[PATCH] ASoC: codecs: make snd_soc_dai_driver and snd_soc_component_driver const

From: Bhumika Goyal
Date: Wed Aug 16 2017 - 13:15:09 EST


Make these two structure variables const as they are either used in a
copy operation or passed to devm_snd_soc_register_component having the
corresponding argument as const.
Done using Coccinelle.
