Subject: [PATCH 4/7] power: supply: bq27xxx: use BIT() for bit flags
Date: Tue, 8 Sep 2020 22:13:16 +0200 [thread overview]
Message-ID: <20200908201319.3567-4-krzk@kernel.org> (raw)
In-Reply-To: <20200908201319.3567-1-krzk@kernel.org>
BIT() is a preferred way to toggle bit-like flags: no problems with 32/64
bit systems, less chances for mistakes.
