Subject: ASoC: Add context parameter to card DAPM callbacks
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=d4c6005;p=linux-beck.git

ASoC: Add context parameter to card DAPM callbacks

The card callback will get called for each DAPM context in the card so it
can be useful for it to know which device is currently undergoing a
transition.
