[PATCH 0/9] mmc: sdhci: code clean-up and fix cache coherency problem.

[Masahiro Yamada]

My main motivation of this series is the last patch
"mmc: sdhci: fix missing cache invalidation after reading by DMA".

Currently, read data are occasionally corrupted due to the
missing cache invalidation.

To fix it nicely (adds dma_unmap_single(), which follows the
Linux coding style), I did some cleaups first.

Patch 01 and 02 fix the prototypes of dma_{map,unmap}_single().

Patch 03-08 are code clean-ups.

Patch 09 fixes the bug.
