iio: core: add missing mutex_destroy in iio_dev_release()

Browse source

[ Upstream commit f5d203467a ]

Add missing mutex_destroy() call in iio_dev_release() to properly
clean up the mutex initialized in iio_device_alloc(). Ensure proper
resource cleanup and follows kernel practices.

Found by code review.

While at it, create a lockdep key before mutex initialisation.
This will help with converting it to the better API in the future.

Fixes: ac917a8111 ("staging:iio:core set the iio_dev.info pointer to null on unregister under lock.")
