tsl2772_read_prox_diodes() will correctly parse the properties from
device tree to determine which proximity diode(s) to read from, however
it didn't actually set this value on the struct tsl2772_settings. Let's
go ahead and fix that.

If a second dummy client that talks to the actual I2C address was
created in probe(), there should be a proper cleanup on driver and
device removal to avoid leakage.

So unregister the dummy client via another callback.

Pull char/misc and other driver subsystem updates from Greg KH:
 "Here is the large set of driver changes for char/misc drivers and
  other smaller driver subsystems that flow through this git tree.

  Included in here are:

   - New IIO drivers and features and improvments in that subsystem

   - New hwtracing drivers and additions to that subsystem

   - lots of interconnect changes and new drivers as that subsystem
     seems under very active development recently. This required also
     merging in the icc subsystem changes through this tree.

   - FPGA driver updates

   - counter subsystem and driver updates

   - MHI driver updates

   - nvmem driver updates

   - documentation updates

   - Other smaller driver updates and fixes, full details in the
     shortlog

  All of these have been in linux-next for a while with no reported
  problems"

Allow more custom IIO sensors through HID (Philipp Jungkamp)

We need the char-misc driver fixes in here as other patches depend on
them.

There are different init functions for the sensors in this driver in
which only one initializes the generic vcnl4000_lock. With commit
e21b5b1f2669 ("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.

Add support to configure proximity sensor interrupts and threshold

This driver supports 4 chips, by which only one (vcnl4010) handles
interrupts and has support for triggered buffer. The setup of these
functions is hardcoded for vcnl4010 inside the generic vcnl4000_probe,
and thus ignores the chip specific configuration structure where all
other chip specific functions are specified.

This complicates adding interrupt handler and triggered buffer support
to chips which may have support for it.

Add members for irq threads and iio_buffer_setup_ops to the generic
vcnl4000_chip_spec struct, so that instead of checking a chip specific
boolean irq support, we check for a chip specific triggered buffer
handler, and/or a chip specific irq thread handler.

In order to allow the chip_spec array reference the function pointers
for interrupts, the code for these functions need to be moved above the
chip_spec array.

This is a prestep to support a more generic setup of interrupts.
