8cd4f58142 Bluetooth: Remove quirk for HCI_VENDOR_PKT filter handling
The HCI_VENDOR_PKT quirk was needed for BPA-100/105 devices that send
these messages. Now that there is support for proper diagnostic channel
this quirk is no longer needed.

9d08f50401 Bluetooth: btusb: Add support for Broadcom LM_DIAG interface
The Broadcom Bluetooth USB devices have a third interface that is
dedicated for LM_DIAG messages. The If#= 2 describes this interface
and it consists of one bulk in and one bulk endpoint.

For all Broadcom based devices with this interface, the driver now
claims it and schedules URBs for it. This allows to capture the
LM_DIAG messages and allows forwarding them via hci_recv_diag into
the diagnostic channel of the Bluetooth subsystem.

bc1d03687b perf cpu_map: Fix core dump caused by per-socket/core system-wide stat
Perf will core dump if --per-socket/core -a are applied for perf stat.

The root cause is that cpu_map__build_map set refcnt of evlist's cpu_map
to 1.  It should set refcnt for the newly created cpu_map, not evlist's
cpu_map.

Here is the example:

  # perf stat -e cycles --per-socket -a sleep 1

   Performance counter stats for 'system wide':

  S0       36         30,196,257      cycles
  S1       28         15,823,536      cycles

3686d3e7d6 clk: shmobile: Add new Renesas CPG/MSSR DT bindings
On Renesas ARM SoCs (SH/R-Mobile, R-Car, RZ), the CPG (Clock Pulse
Generator) and MSSR (Module Standby and Software Reset) blocks are
intimately connected, and share the same register block.

Hence it makes sense to describe these two blocks using a
single device node in DT, instead of using a hierarchical structure with
multiple nodes, using a mix of generic and SoC-specific bindings.

These new DT bindings are intended to replace the existing DT bindings
for CPG core clocks ("renesas,*-cpg-clocks", "renesas,cpg-div6-clock")
and module clocks ("renesas,*-mstp-clocks"), at least for new SoCs.

This will make it easier to add module reset support later, which is
currently not implemented, and difficult to achieve using the existing
bindings due to the intertwined register layout.

ab3964ad2a IB/cma: Use inner P_Key to determine netdev
When discussing the patches to demux ids in rdma_cm instead of ib_cm, it
was decided that it is best to use the P_Key value in the packet headers.
However, the mlx5 and ipath drivers are currently unable to send correct
P_Key values in GMP headers. They always send using a single P_Key that is
set during the GSI QP initialization.

Change the rdma_cm code to look at the P_Key value that is part of the
packet payload as a workaround. Once the drivers are fixed this patch can
be reverted.

759b26a1d9 [media] media/v4l2-ctrls: fix setting autocluster to manual with VIDIOC_S_CTRL
Since commit 5d0360a4f0 it's not possible
anymore to set auto clusters from auto to manual using VIDIOC_S_CTRL.

For example, setting autogain to manual with gspca/ov534 driver and this
sequence of commands does not work:

  v4l2-ctl --set-ctrl=gain_automatic=1
  v4l2-ctl --list-ctrls | grep gain_automatic
  # The following does not work
  v4l2-ctl --set-ctrl=gain_automatic=0
  v4l2-ctl --list-ctrls | grep gain_automatic

Changing the value using VIDIOC_S_EXT_CTRLS (like qv4l2 does) works
fine.

The apparent cause by looking at the changes in 5d0360a and comparing
with the code path for VIDIOC_S_EXT_CTRLS seems to be that the code in
v4l2-ctrls.c::set_ctrl() is not calling user_to_new() anymore after
calling update_from_auto_cluster(master).

However the root cause of the problem is that calling
update_from_auto_cluster(master) overrides also the _master_ control
state calling cur_to_new() while it was supposed to only update the
volatile controls.

Calling user_to_new() after update_from_auto_cluster(master) was just
masking the original bug by restoring the correct new value of the
master control before making the changes permanent.

Fix the original bug by making update_from_auto_cluster() not override
the new master control value.

41018cb84a [media] v4l2: add RF gain control
Add new RF tuner gain control named RF Gain. That is aimed for first
amplifier chip right after antenna connector.
There is existing LNA Gain control, which is quite same, but it is
aimed for cases amplifier is integrated to tuner chip. Some designs
have both, as almost all recent tuner silicons has integrated LNA/RF
amplifier in any case.

f3c3ecec97 [media] v4l2: rename V4L2_TUNER_ADC to V4L2_TUNER_SDR
SDR receiver has ADC (Analog-to-Digital Converter) and SDR transmitter
has DAC (Digital-to-Analog Converter). Originally I though it could
be good idea to have own type for receiver and transmitter, but now I
feel one common type for SDR is enough. So lets rename it.

f06d89028b [media] smiapp: Export OF module alias information
The I2C core always reports the MODALIAS uevent as "i2c:<client name"
regardless if the driver was matched using the I2C id_table or the
of_match_table. So technically there's no need for a driver to export
the OF table since currently it's not used.

In fact, the I2C device ID table is mandatory for I2C drivers since
a i2c_device_id is passed to the driver's probe function even if the
I2C core used the OF table to match the driver.

And since the I2C core uses different tables, OF-only drivers needs to
have duplicated data that has to be kept in sync and also the dev node
compatible manufacturer prefix is stripped when reporting the MODALIAS.

To avoid the above, the I2C core behavior may be changed in the future
to not require an I2C device table for OF-only drivers and report the
OF module alias. So, it's better to also export the OF table to prevent
breaking module autoloading if that happens.
