staging: iio: adc: ad7192: use driver private lock to protect hardware state changes
The IIO subsystem is redefining iio_dev->mlock to be used by
the IIO core only for protecting device operating mode changes.
ie. Changes between INDIO_DIRECT_MODE, INDIO_BUFFER_* modes.
In this driver, mlock was being used to protect hardware state
changes. Replace it with a driver private lock.
Also, as there are state changes in the ad7192_ write_raw function, a lock
is added to prevent the concurrent state changes.
