From 809390219fb9c2421239afe5c9eb862d73978ba0 Mon Sep 17 00:00:00 2001 From: Andy Shevchenko Date: Thu, 25 Feb 2021 18:33:19 +0200 Subject: gpiolib: acpi: Allow to find GpioInt() resource by name and index Currently only search by index is supported. However, in some cases we might need to pass the quirks to the acpi_dev_gpio_irq_get(). For this, split out acpi_dev_gpio_irq_get_by() and replace acpi_dev_gpio_irq_get() by calling above with NULL for name parameter.
