Subject: [PATCH v1 7/8] iio: accel: bma220: Use BIT() and GENMASK() macros
Date: Mon, 31 Aug 2020 12:08:12 +0300	[thread overview]
Message-ID: <20200831090813.78841-7-andriy.shevchenko@linux.intel.com> (raw)
In-Reply-To: <20200831090813.78841-1-andriy.shevchenko@linux.intel.com>

Code is better to read when numbers of bit are explicitly used.
