Subject[PATCH 4.10 103/111] mmc: block: Fix is_waiting_last_req set incorrectly
Date
4.10-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Adrian Hunter <adrian.hunter@intel.com>

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.

Fixes: 15520111500c ("mmc: core: Further fix thread wake-up")
