From: Ludovic Barre <ludovic.barre@xxxxxx> As discussed in this thread: https://patchwork.kernel.org/patch/10786421/ After a request, the host could be in deadlock state, and waiting for a specific action to unstuck the hardware block before resending a new command. This series adds mmc_hw_unstuck callback (structure mmc_host_ops) before resending a new command (call in mmc_blk_mq_rw_recovery, mmc_wait_for_req_done).
