Kishon Vijay Abraham I 408806f740 mmc: omap_hsmmc: Fix DTO and DCRC handling ... DTO/DCRC errors were not being informed to the mmc core since commit ae4bf788ee ("mmc: omap_hsmmc: consolidate error report handling of HSMMC IRQ"). This commit made sure 'end_trans' is never set on DTO/DCRC errors. This is because after this commit 'host->data' is checked after it has been cleared to NULL by omap_hsmmc_dma_cleanup(). Because 'end_trans' is never set, omap_hsmmc_xfer_done() is never invoked making core layer not to be aware of DTO/DCRC errors. Because of this any command invoked after DTO/DCRC error leads to a hang. Fix this by checking for 'host->data' before it is actually cleared.
