[alsa-devel] [PATCH 1/2] ASoC: sh: rcar: core: don't open code of_device_get_match_data()

From: Wolfram Sang <wsa+renesas at sang-engineering.com>

This change will also make Coverity happy by avoiding a theoretical NULL
pointer dereference; yet another reason is to use the above helper function
to tighten the code and make it more readable.

Compile tested only. I am on the road and can't test the multimedia drivers
because of no cables :( If someone could test it, that would be much
appreciated. Or I'll do it next week. The pattern worked for other drivers
I could actually test, though.
