Subject: [PATCH v2 0/2] Remove the IIO counter ABI

Changes in v2:
 - Add missing argument to devm_kzalloc() call in quad8_probe().
 - Remove superfluous 'err' variable from quad8_probe().

The IIO counter driver has been superseded by the Counter subsystem as
discussed in [1]. This patchset removes the IIO counter ABI code and
documentation.

A patch to remove the IIO counter ABI code from the stm32-lptimer-cnt
counter driver has been submitted to the list separately [2]; if you
would like me to combine it with this patchset, please let me know.

One final user of the IIO counter ABI code is still remaining for now:
drivers/iio/trigger/stm32-timer-trigger.c. Is this driver related to the
drivers/counter/stm32-timer-cnt.c driver? Can it be migrated to the
Counter subsystem ABI instead?
