Subject: [PATCH v8 08/11] input: raspberrypi-ts: Release firmware handle when not needed
Date: Fri, 12 Mar 2021 13:24:51 +0100	[thread overview]
Message-ID: <20210312122454.24480-9-nsaenzjulienne@suse.de> (raw)
In-Reply-To: <20210312122454.24480-1-nsaenzjulienne@suse.de>

There is no use for the firmware interface after getting the touch
buffer address, so release it.
