Subject: [PATCH 2/6] gpio: mockup: implement get_multiple()
Date: Mon, 18 Feb 2019 10:47:55 +0100 [thread overview]
Message-ID: <20190218094759.14545-3-brgl@bgdev.pl> (raw)
In-Reply-To: <20190218094759.14545-1-brgl@bgdev.pl>
From: Bartosz Golaszewski <bgolaszewski@baylibre.com>
We already support set_multiple(). Implement get_multiple() as well.
