ASoC: codecs: make snd_soc_dai_driver and snd_soc_component_driver const

goyalbhumika · broonie · commit 6e37f933ed1a · 2017-08-17T18:10:34.000+01:00
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.
