+Subject: ASoC: wm8960: Fix PLL register writes
+
+From: Mike Dyer <mike.dyer@md-soft.co.uk>
+
+commit 85fa532b6ef920b32598df86b194571a7059a77c upstream.
+
+Bit 9 of PLL2,3 and 4 is reserved as '0'. The 24bit fractional part
+should be split across each register in 8bit chunks.

+Subject: rculist: list_first_or_null_rcu() should use list_entry_rcu()
+
+From: Tejun Heo <tj@kernel.org>
+
+commit c34ac00caefbe49d40058ae7200bd58725cebb45 upstream.
+
+list_first_or_null() should test whether the list is empty and return
+pointer to the first entry if not in a RCU safe manner. It's broken
+in several ways.
+
+* It compares __kernel @__ptr with __rcu @__next triggering the
+ following sparse warning.
+
+ net/core/dev.c:4331:17: error: incompatible types in comparison expression (different address spaces)
+
+* It doesn't perform rcu_dereference*() and computes the entry address
+ using container_of() directly from the __rcu pointer which is
+ inconsitent with other rculist interface. As a result, all three
+ in-kernel users - net/core/dev.c, macvlan, cgroup - are buggy. They
+ dereference the pointer w/o going through read barrier.
+
+* While ->next dereference passes through list_next_rcu(), the
+ compiler is still free to fetch ->next more than once and thus
+ nullify the "__ptr != __next" condition check.
+
+Fix it by making list_first_or_null_rcu() dereference ->next directly
+using ACCESS_ONCE() and then use list_entry_rcu() on it like other
+rculist accessors.
+
+v2: Paul pointed out that the compiler may fetch the pointer more than
+ once nullifying the condition check. ACCESS_ONCE() added on
+ ->next dereference.
+
+v3: Restored () around macro param which was accidentally removed.
+ Spotted by Paul.

+From: Hans de Goede <hdegoede@redhat.com>
+
+commit b4f17a488ae2e09bfcf95c0e0b4219c246f1116a upstream.
+
+While reading the config parsing code I noticed this check is missing, without
+this check config->desc.wTotalLength can end up with a value larger then the
+dev->rawdescriptors length for the config, and when userspace then tries to
+get the rawdescriptors bad things may happen.
