mmc: at91_mci: modify cache flush routines
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. [akpm@linux-foundation.org: flush_kernel_dcache_page() comes before kunmap_atomic()] Signed-off-by: Nicolas Ferre <nicolas.ferre@atmel.com> Cc: James Bottomley <James.Bottomley@HansenPartnership.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
