Subject: [PATCH v2 07/14] spi: pxa2xx: Introduce int_stop_and_reset() helper
Date:   Fri, 23 Apr 2021 21:24:34 +0300
Message-Id: <20210423182441.50272-8-andriy.shevchenko@linux.intel.com>
In-Reply-To: <20210423182441.50272-1-andriy.shevchenko@linux.intel.com>

Precedence: bulk

Currently we have three times the same few lines repeated in the code.
Deduplicate them by newly introduced int_stop_and_reset() helper.
