-Subject: [PATCH v2] spi: lantiq-ssc: Fix warning by using WQ_MEM_RECLAIM
-
-The lantiq-ssc driver uses internally an own workqueue to wait till the
-data is not only written out of the FIFO but really written to the wire.
-This workqueue is flushed while the SPI subsystem is working in some
-other system workqueue.
-
-The system workqueue is marked as WQ_MEM_RECLAIM, but the workqueue in
-the lantiq-ssc driver does not use WQ_MEM_RECLAIM for now. Add this flag
-too to prevent this warning.
-
-This fixes the following warning:
-[    2.975956] WARNING: CPU: 1 PID: 17 at kernel/workqueue.c:2614 check_flush_dependency+0x168/0x184
-[    2.984752] workqueue: WQ_MEM_RECLAIM kblockd:blk_mq_run_work_fn is flushing !WQ_MEM_RECLAIM 1e100800.spi:0x0
-
-Fixes: 891b7c5fbf61 ("mtd_blkdevs: convert to blk-mq")
