Subject: [PATCH 3/6] udoo: Call gpio_request()
Date: Sat, 18 Dec 2021 18:10:22 -0300 [thread overview]
Message-ID: <20211218211025.770362-3-festevam@gmail.com> (raw)
In-Reply-To: <20211218211025.770362-1-festevam@gmail.com>
Calling gpio_request() prior to its usage is now mandatory.
This fixes the following GPIO errors:
