Subject: [PATCH v1 1/2] pinctrl: baytrail: Use platform_get_irq_optional() explicitly
Date: Tue, 14 Apr 2020 19:13:37 +0300 [thread overview]
Message-ID: <20200414161338.3025-1-andriy.shevchenko@linux.intel.com> (raw)
There is no need to repeat functionality of platform_get_irq_optional()
in the driver. Replace it with explicit call to the helper.
