+Subject: [PATCH] ALSA: usb-audio: Fix the missing ctl name suffix at parsing
+ SU
+
+The commit 89b89d121ffc ("ALSA: usb-audio: Add check return value for
+usb_string()") added the check of the return value from
+snd_usb_copy_string_desc(), which is correct per se, but it introduced
+a regression.  In the original code, either the "Clock Source",
+"Playback Source" or "Capture Source" suffix is added after the
+terminal string, while the commit changed it to add the suffix only
+when get_term_name() is failing.  It ended up with an incorrect ctl
+name like "PCM" instead of "PCM Capture Source".
+
+Also, even the original code has a similar bug: when the ctl name is
+generated from snd_usb_copy_string_desc() for the given iSelector, it
+also doesn't put the suffix.
+
+This patch addresses these issues: the suffix is added always when no
+static mapping is found.  Also the patch tries to put more comments
+and cleans up the if/else block for better readability in order to
+avoid the same pitfall again.
+
+Fixes: 89b89d121ffc ("ALSA: usb-audio: Add check return value for usb_string()")

+ lookup.
+
+When we do tunnel or beet mode, we pass saddr and daddr from the
+template to xfrm_state_find(), this is ok. On transport mode,
+we pass the addresses from the flowi, assuming that the IP
+addresses (and address family) don't change during transformation.
+This assumption is wrong in the IPv4 mapped IPv6 case, packet
+is IPv4 and template is IPv6.
+
+Fix this by catching address family missmatches of the policy
+and the flow already before we do the lookup.

+Subject: [PATCH 3/3] cgroup: fix css_task_iter crash on CSS_TASK_ITER_PROC
+
+While teaching css_task_iter to handle skipping over tasks which
+aren't group leaders, bc2fb7ed089f ("cgroup: add @flags to
+css_task_iter_start() and implement CSS_TASK_ITER_PROCS") introduced a
+silly bug.
+
+CSS_TASK_ITER_PROCS is implemented by repeating
+css_task_iter_advance() while the advanced cursor is pointing to a
+non-leader thread.  However, the cursor variable, @l, wasn't updated
+when the iteration has to advance to the next css_set and the
+following repetition would operate on the terminal @l from the
+previous iteration which isn't pointing to a valid task leading to
+oopses like the following or infinite looping.
