23fd6f0bd6 iio: accel: st_accel: Add LSM303C 
The accelerometer part of ST LSM303C is similar (perhaps even identical)
to the already supported standalone LIS2HH12 accelerometer, so just
add the new st,lsm303c-accel compatible for the existing definitions.

4aaf3e4027 dt-bindings: iio: st-sensors: Add LSM303C accelerometer+magnetometer 
The ST LSM303C [1] is a accelerometer and magnetometer combo sensor
compatible with the existing ST sensor bindings. Accelerometer and
magnetometer are exposed through separate I2C/SPI devices, so document
separate compatibles with -accel and -magn suffix.

0410484273 iio: adc: qcom-spmi-adc5: Suppress probe-deferral error message 
Much like 807efb7102e8 ("thermal: qcom-spmi-adc-tm5: suppress
probe-deferral error message") the ADC5 driver also spams a similar
probe-deferral error on startup when a channel is not yet available:

    [    0.343136] qcom-spmi-adc-tm5 1c40000.spmi:pmic@0:adc-tm@3500: get dt data failed: -517

Suppress it by using dev_err_probe instead, which also takes care of
storing the message as reason for deferring.

866a138917 iio: magnetometer: add ti tmag5273 driver 
Add support for TI TMAG5273 Low-Power Linear 3D Hall-Effect Sensor.
Additionally to temperature and magnetic X, Y and Z-axes the angle and
magnitude are reported.
The sensor is operating in continuous measurement mode and changes to sleep
mode if not used for 5 seconds.

292a089d78 treewide: Convert del_timer*() to timer_shutdown*() 
Due to several bugs caused by timers being re-armed after they are
shutdown and just before they are freed, a new state of timers was added
called "shutdown".  After a timer is set to this state, then it can no
longer be re-armed.

The following script was run to find all the trivial locations where
del_timer() or del_timer_sync() is called in the same function that the
object holding the timer is freed.  It also ignores any locations where
the timer->function is modified between the del_timer*() and the free(),
as that is not considered a "trivial" case.

This was created by using a coccinelle script and the following
commands:

    $ cat timer.cocci
    @@
    expression ptr, slab;
    identifier timer, rfield;
    @@
    (
    -       del_timer(&ptr->timer);
    +       timer_shutdown(&ptr->timer);
    |
    -       del_timer_sync(&ptr->timer);
    +       timer_shutdown_sync(&ptr->timer);
    )
      ... when strict
          when != ptr->timer
    (
            kfree_rcu(ptr, rfield);
    |
            kmem_cache_free(slab, ptr);
    |
            kfree(ptr);
    )

    $ spatch timer.cocci . > /tmp/t.patch
    $ patch -p1 < /tmp/t.patch
