H A D | dw_mmc.c | diff aa50f259d65603f40a82ef0d256a6a954a3db283 Fri Aug 30 17:14:38 CEST 2013 Seungwon Jeon <tgih.jun@samsung.com> mmc: dw_mmc: fix the transfer termination in IDMAC mode
In IDMAC mode EVENT_XFER_COMPLETE is set when RI/TI of last descriptor is done. So if errors are happened in the middle of data transfers, 'dw_mci_stop_dma' during error handing can be called and eventually prevents this flag to be set. This results in permanent wait for EVENT_XFER_COMPLETE in 'dw_mci_tasklet_func'. Therefore, if dma running is stopped forcibly, EVENT_XFER_COMPLETE should be set.
