Subject: ASoC: fsl: register the wm9712-codec
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=c912fa913446b07147f6cbc1a8fa2fb20d2f7c36;p=linux-beck.git

ASoC: fsl: register the wm9712-codec

The mpc5200-psc-ac97 driver does not enumerate attached ac97 devices, so
register the device here.
