Mårten Lindahl 42ec40b088 iio: light: vcnl4000: Fix WARN_ON on uninitialized lock 
There are different init functions for the sensors in this driver in
which only one initializes the generic vcnl4000_lock. With commit
e21b5b1f26 ("iio: light: vcnl4000: Preserve conf bits when toggle power")
the vcnl4040 sensor started to depend on the lock, but it was missed to
initialize it in vcnl4040's init function. This has not been visible
until we run lockdep on it:

  DEBUG_LOCKS_WARN_ON(lock->magic != lock)
  at kernel/locking/mutex.c:575 __mutex_lock+0x4f8/0x890
  Call trace:
  __mutex_lock
  mutex_lock_nested
  vcnl4200_set_power_state
  vcnl4200_init
  vcnl4000_probe

Fix this by initializing the lock in the probe function instead of doing
it in the chip specific init functions.

README 

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
