Subject: ASoC: dapm: Add a helper function to free a DAPM path
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=8872293fc38c4906c86e7d335b8f936abf9e4531;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

ASoC: dapm: Add a helper function to free a DAPM path

We have the same code for freeing a DAPM path in three different locations.
Introduce a new helper function to take care of this.
