Subject: [PATCH v4 07/10] input: keyboard: adp5588-keys: fix coding style warnings
Date:   Mon, 29 Aug 2022 15:15:50 +0200
Message-ID: <20220829131553.690063-8-nuno.sa@analog.com>
In-Reply-To: <20220829131553.690063-1-nuno.sa@analog.com>

Content-Type: text/plain; charset="UTF-8"
Content-Transfer-Encoding: 8bit
Precedence: bulk

Just some code cleanup regarding coding style. With the introduction of
the bits.h macros changes in the code are indeed introduced.
