Subject: [PATCH v2 7/9] pwm: lpss: Make use of bits.h macros for all masks
Date: Thu, 8 Sep 2022 16:56:56 +0300 [thread overview]
Message-ID: <20220908135658.64463-8-andriy.shevchenko@linux.intel.com> (raw)
In-Reply-To: <20220908135658.64463-1-andriy.shevchenko@linux.intel.com>
Make use of the GENMASK() (far less error-prone, far more concise).
