[PATCH] iio: mxs-lradc: fix error handling in mxs_lradc_probe()

From: Alexey Khoroshilov
Date: Fri Dec 23 2016 - 17:15:38 EST


During transition to using devm_input_allocate_device()
goto to resource deallocation block was replaced by return
in case of error in iio_device_register().
That is wrong since resources are left undeallocated.

Found by Linux Driver Verification project (linuxtesting.org).
