Subject: [PATCH 07/14] nvmem: release the write-protect pin
Date: Tue, 10 Mar 2020 13:22:50 +0000	[thread overview]
Message-ID: <20200310132257.23358-8-srinivas.kandagatla@linaro.org> (raw)
In-Reply-To: <20200310132257.23358-1-srinivas.kandagatla@linaro.org>

From: Khouloud Touil <ktouil@baylibre.com>

Put the write-protect GPIO descriptor in nvmem_release() so that it can
be automatically released when the associated device's reference count
drops to 0.

Fixes: 2a127da461a9 ("nvmem: add support for the write-protect pin")
