Subject: ASoC: dapm - Make DAPM reset code a separate function.
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=6c120e19fa587710d80757a6e364961a017fb6c3;p=openwrt%2Fstaging%2Fblogic.git

ASoC: dapm - Make DAPM reset code a separate function.

It's useful to export the DAPM reset as a static function for future use
by other DAPM functions. e.g. The dynamic PCM query widgets resets the DAPM
graph before working out active paths.
