From ca4cf5ea04d2e126177d487b874aa19267277e4a Mon Sep 17 00:00:00 2001 From: Serge Semin Date: Thu, 30 Jul 2020 18:28:03 +0300 Subject: [PATCH] gpio: dwapb: Discard GPIO-to-IRQ mapping function Since GPIOlib-based IRQ-chip interface is now utilized there is no need in setting up a custom GPIO-to-IRQ mapping method. GPIO-lib defines the standard mapping method - gpiochip_to_irq(), which will be used anyway no matter whether the custom to_irq callback is specified or not.
