ASoC: dpcm: print dai_link name of BE other than FE.
When operating the BE, we should print out the dai_link name of BE other than FE. This is useful when analyzing the kernel log. Signed-off-by: Donglin Peng <pengdonglin@smartisan.com> Signed-off-by: Mark Brown <broonie@kernel.org>

afe lock
Reports have surfaced of a lockdep splat complaining about an irq-safe -> irq-unsafe locking order in the xfs_buf_bio_end_io() bio completion handler. This only occurs when I/O errors are present because bp->b_lock is only acquired in this context to protect setting an error on the buffer. The problem is that this lock can be acquired with the (request_queue) q->queue_lock held. See scsi_end_request() or ata_qc_schedule_eh(), for example. Replace the locked test/set of b_io_error with a cmpxchg() call. This eliminates the need for the lock and thus the lock ordering problem goes away.
