Subject: [PATCH 05/40] hwmon: (lm90) Use BIT macro
Date:   Wed, 25 May 2022 06:57:23 -0700
Message-Id: <20220525135758.2944744-6-linux@roeck-us.net>
In-Reply-To: <20220525135758.2944744-1-linux@roeck-us.net>
References: <20220525135758.2944744-1-linux@roeck-us.net>
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit
Precedence: bulk

Use BIT macro instead of shift operation to improve readability.
No functional change.
