Subject: [PATCH v1 11/14] spi: pxa2xx: Extract clear_SSCR1_bits() helper
Date: Fri, 23 Apr 2021 19:34:34 +0300	[thread overview]
Message-ID: <20210423163437.89306-11-andriy.shevchenko@linux.intel.com> (raw)
In-Reply-To: <20210423163437.89306-1-andriy.shevchenko@linux.intel.com>

There are few places that repeat the logic of "clear some bits in SSCR1".
Extract clear_SSCR1_bits() helper to deduplicate that.
