mmc: tmio: fix recursive spinlock, don't schedule with interrupts disabled

Browse source

Calling mmc_request_done() under a spinlock with interrupts disabled
leads to a recursive spin-lock on request retry path and to
scheduling in atomic context. This patch fixes both these problems
by moving mmc_request_done() to the scheduler workqueue.
