6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Joe Hattori <joe@xxxxxxxxxxxxxxxxxxxxx>
commit de6a73bad1743e9e81ea5a24c178c67429ff510b upstream.
Current implementation of at91_ts_register() calls input_free_deivce()
on st->ts_input, however, the err label can be reached before the
allocated iio_dev is stored to st->ts_input. Thus call
input_free_device() on input instead of st->ts_input.
