[PATCH v5 4/8] drivers: thermal: tsens: Release device in success path

From: Amit Kucheria
Date: Tue Feb 18 2020 - 13:12:41 EST


We don't currently call put_device in case of successfully initialising
the device.

Allow control to fall through so we can use same code for success and
error paths to put_device.

As a part of this fixup, change devm_ioremap_resource to act on the same
device pointer as that used to allocate regmap memory. That ensures that
we are free to release op->dev after examining its resources.
