Subject: ASoC: Add card driver data
X-Git-Tag: upstream/snapshot3+hdmi~7307^2~1226^2~27
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=dddf3e4c257879bc35cda3f542507c43f2648a2a;p=platform%2Fadaptation%2Frenesas_rcar%2Frenesas_kernel.git

ASoC: Add card driver data

Provide driver data for cards within the card structure. To simplify the
implementation of the PM operations we don't use the struct device driver
data as this is used by the core to retrieve the card in callbacks from
the device model and PM core.
