Subject: [PATCH v1 2/5] pinctrl: stm32: Replace custom code by gpiochip_count() call
Date: Fri, 25 Mar 2022 22:03:35 +0200	[thread overview]
Message-ID: <20220325200338.54270-2-andriy.shevchenko@linux.intel.com> (raw)
In-Reply-To: <20220325200338.54270-1-andriy.shevchenko@linux.intel.com>

Since we have generic function to count GPIO controller nodes
under given device, there is no need to open code it. Replace
custom code by gpiochip_count() call.
