Subject: [PATCH v2 net-next 1/1] ptp_ocp: use bits.h macros for all masks
Date: Tue, 17 Aug 2021 15:24:54 +0300	[thread overview]
Message-ID: <20210817122454.50616-1-andriy.shevchenko@linux.intel.com> (raw)

Currently we are using BIT(), but GENMASK(). Make use of the latter one
as well (far less error-prone, far more concise).
