Subject: [PATCH 15/22] Input: rb532_button - switch to using managed resources
Date: Thu, 17 Oct 2019 13:42:09 -0700	[thread overview]
Message-ID: <20191017204217.106453-16-dmitry.torokhov@gmail.com> (raw)
In-Reply-To: <20191017204217.106453-1-dmitry.torokhov@gmail.com>

Using devm API allows us to clean up error handling paths and drop the
remove() method.
