From 4bef8bf20b69c3a98dbb9c8e406c22adb8fd3903 Mon Sep 17 00:00:00 2001 From: Linus Walleij Date: Mon, 3 Sep 2018 09:59:57 +0200 Subject: [PATCH] gpio: twl6040: Use bitops It's nice to use BIT() macros rather than open coding the same. It's good practice as sometimes people use BIT(31) and forget that the constant must be cast unsigned long.
