mmc: host: create a specific workqueue for clk gate mmc host clock gate work was scheduled on system_wq, which is created without flag WQ_MEM_RECLAIM. Because mmcqd thread was created with flag PF_MEMALLOC set, it would break forward-progress guarantee leading to a deadlock when clock gate work is cancelled. Fix it by creating a specific work queue for clock gate work. Change-Id: I4be5d629c712d8c48049f1e2df2c14ac6024b837 Signed-off-by: Can Guo <cang@codeaurora.org>
