Subject: [PATCH v2 5/5] Input: adp5589: use devm_add_action_or_reset() for register clear
Date: Thu, 12 Nov 2020 09:43:08 +0200	[thread overview]
Message-ID: <20201112074308.71351-6-alexandru.ardelean@analog.com> (raw)
In-Reply-To: <20201112074308.71351-1-alexandru.ardelean@analog.com>

The driver clears the general configuration register during the remove()
hook. This should also be done in case the driver exits on error.

This change move the clear of that register to the
devm_add_action_or_reset() hook.
