If anyone has any objections, please let me know. ------------------ From: Adrian Hunter commit 2602b740e45cc64feb55d5a9ee8db744ab3becbb upstream. Commit 15520111500c ("mmc: core: Further fix thread wake-up") allowed a queue to release the host with is_waiting_last_req set to true. A queue waiting to claim the host will not reset it, which can result in the queue getting stuck in a loop.
