Subject: [PATCH 05/13] nvmem: change the signature of nvmem_unregister()
Date: Wed, 5 Sep 2018 11:57:30 +0200 [thread overview]
Message-ID: <20180905095738.26406-6-brgl@bgdev.pl> (raw)
In-Reply-To: <20180905095738.26406-1-brgl@bgdev.pl>
From: Bartosz Golaszewski <bgolaszewski@baylibre.com>
This function can no longer fail and there are no more users that check
it return value. Change it to return void.
