[PATCH 2/6] Staging: iio: cdc: ad7152.c: Prefer using the BIT macro

From: Shraddha Barke
Date: Thu Sep 10 2015 - 00:14:28 EST


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)
