Subject: [PATCH 2/6] Staging: iio: cdc: ad7152.c: Prefer using the BIT macro
Date: Thu, 10 Sep 2015 09:43:50 +0530 [thread overview]
Message-ID: <1441858434-2846-2-git-send-email-shraddha.6596@gmail.com> (raw)
In-Reply-To: <1441858434-2846-1-git-send-email-shraddha.6596@gmail.com>
This patch replaces bit shifting on 1 with the BIT(x) macro
as it's extensively used by other function in this driver.
This was done with coccinelle:
@@ int g; @@
-(1 << g)
+BIT(g)
