[alsa-devel] [PATCH] ASoC: fsl_ssi: Add missing __iomem annotations

[Lars-Peter Clausen]

There are two places in the fsl_ssi driver where the pointer to the register set
is missing the __iomem annotation. Adding it fixes the following warnings from
sparse:
	sound/soc/fsl/fsl_ssi.c:747:45: warning: incorrect type in initializer (different address spaces)
