to remove the redundant assignment.

Currently the pointer wilc is being null checked several times
and yet not checked for the final workqueue flush and destroy
(which can lead to a null pointer dereference if wilc is null);
these missing null checks were overlooked in an earlier core
refactoring commit.
Clean up the code by checking wilc at the start and bailing out
early if it is null allowing the subsequent null checks to be
removed, this also fixes the potential null pointer deferences
on the workqueue flush and destroy calls.

There is a merge commit in here to pull in regmap support for repeatedly
reading the same register (to read out FIFOs). Used by the adxl372 driver.
This will find uses elsewhere once we tidy up various drivers that are
effectively doing this and relying on not enabling regcache.
New device support
* Analog devices ADXL372 accelerometer
- new driver for this accelerometer including fifo and and interrupt support.
Follow up patches enforce trigger validation, add sampling frequency
control and filter bandwidth control. A later series added i2c support
to the existing SPI support.
* ST lsm6dsx
