Subject: ASoC: stm: stm32_adfsdm: set debugfs_prefix via Component driver
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=d7c18d15c6d93ffcaaaa0c68c31122293c9d1dde;p=thirdparty%2Flinux.git

ASoC: stm: stm32_adfsdm: set debugfs_prefix via Component driver

We can set component->debugfs_prefix via component_driver->debugfs_prefix.
Use it.

Now it no longer need to use snd_soc_component_initialize() /
snd_soc_component_add(). Use snd_soc_component_register() instead.
