Subject: [PATCH 2/6] Input: adp5589: use devm_kzalloc() to allocate the kpad object
Date: Wed, 11 Nov 2020 10:48:29 +0200 [thread overview]
Message-ID: <20201111084833.40995-3-alexandru.ardelean@analog.com> (raw)
In-Reply-To: <20201111084833.40995-1-alexandru.ardelean@analog.com>
This removes the need to manually free the kpad object and cleans up some
exit/error paths.
The error path cleanup should reduce the risk of any memory leaks with this
object.
