mmc: at91_mci: modify cache flush routines

bdef2fe8 · Nicolas Ferre <[email protected]> · 2010-05-15 12:32:31 -04:00

As we were using an internal dma flushing routine, this patch changes to
the DMA API flush_kernel_dcache_page().  Driver is able to compile now.

[[email protected]: flush_kernel_dcache_page() comes before kunmap_atomic()]
