+Subject: ALSA: hda/realtek - PCI quirk for Medion E4254
+
+From: Jan-Marek Glogowski <glogow@fbihome.de>
+
+[ Upstream commit bd9c10bc663dd2eaac8fe39dad0f18cd21527446 ]
+
+The laptop has a combined jack to attach headsets on the right.
+The BIOS encodes them as two different colored jacks at the front,
+but otherwise it seems to be configured ok. But any adaption of
+the pins config on its own doesn't fix the jack detection to work
+in Linux. Still Windows works correct.
+
+This is somehow fixed by chaining ALC256_FIXUP_ASUS_HEADSET_MODE,
+which seems to register the microphone jack as a headset part and
+also results in fixing jack sensing, visible in dmesg as:
+
+-snd_hda_codec_realtek hdaudioC0D0: Mic=0x19
++snd_hda_codec_realtek hdaudioC0D0: Headset Mic=0x19
+
+[ Actually the essential change is the location of the jack; the
+ driver created "Front Mic Jack" without the matching volume / mute
+ control element due to its jack location, which confused PA.

+Subject: blk-mq: add callback of .cleanup_rq
+
+From: Ming Lei <ming.lei@redhat.com>
+
+[ Upstream commit 226b4fc75c78f9c497c5182d939101b260cfb9f3 ]
+
+SCSI maintains its own driver private data hooked off of each SCSI
+request, and the pridate data won't be freed after scsi_queue_rq()
+returns BLK_STS_RESOURCE or BLK_STS_DEV_RESOURCE. An upper layer driver
+(e.g. dm-rq) may need to retry these SCSI requests, before SCSI has
+fully dispatched them, due to a lower level SCSI driver's resource
+limitation identified in scsi_queue_rq(). Currently SCSI's per-request
+private data is leaked when the upper layer driver (dm-rq) frees and
+then retries these requests in response to BLK_STS_RESOURCE or
+BLK_STS_DEV_RESOURCE returns from scsi_queue_rq().
+
+This usecase is so specialized that it doesn't warrant training an
+existing blk-mq interface (e.g. blk_mq_free_request) to allow SCSI to
+account for freeing its driver private data -- doing so would add an
+extra branch for handling a special case that all other consumers of
+SCSI (and blk-mq) won't ever need to worry about.
+
+So the most pragmatic way forward is to delegate freeing SCSI driver
+private data to the upper layer driver (dm-rq). Do so by adding
+new .cleanup_rq callback and calling a new blk_mq_cleanup_rq() method
+from dm-rq. A following commit will implement the .cleanup_rq() hook
+in scsi_mq_ops.

+Subject: scsi: implement .cleanup_rq callback
+
+From: Ming Lei <ming.lei@redhat.com>
+
+[ Upstream commit b7e9e1fb7a9227be34ad4a5e778022c3164494cf ]
+
+Implement .cleanup_rq() callback for freeing driver private part
+of the request. Then we can avoid to leak this part if the request isn't
+completed by SCSI, and freed by blk-mq or upper layer(such as dm-rq) finally.
