mmc: tmio: always unmap DMA before waiting for interrupt
In the (maybe academical) case, we don't get a DATAEND interrupt after DMA completed, we will wait endlessly for the completion to complete. This is not bad per se, since we have a more generic completion tracking a timeout. In that rare case, however, the DMA buffer will not get unmapped and we have a leak. Reorder the code, so unmapping will always take place. Signed-off-by:Wolfram Sang <wsa+renesas@sang-engineering.com> Signed-off-by:
