Subject: [PATCH] counter/ftm-quaddec: Use device-managed registration API
Date: Thu, 25 Jul 2019 16:54:58 +0800 [thread overview]
Message-ID: <20190725085458.21838-1-hslester96@gmail.com> (raw)
Make use of devm_counter_register.
Then we can remove redundant unregistration API
usage to make code simpler.
