Subject: [PATCH v3 2/4] gpio: dwapb: avoid error message for optional IRQ
Date: Tue, 19 May 2020 16:12:31 +0300 [thread overview]
Message-ID: <20200519131233.59032-2-andriy.shevchenko@linux.intel.com> (raw)
In-Reply-To: <20200519131233.59032-1-andriy.shevchenko@linux.intel.com>
platform_get_irq() will generate an error message if the requested IRQ
is not present. Use platform_get_irq_optional() to avoid the error message
being generated.
