From a947aa00edd4d465f89fdb6029ed40c00a344bc2 Mon Sep 17 00:00:00 2001 From: Neil Armstrong Date: Thu, 2 Sep 2021 15:49:13 +0200 Subject: [PATCH] irqchip/meson-gpio: Make it possible to build as a module In order to reduce the kernel Image size on multi-platform distributions, make it possible to build the Amlogic GPIO IRQ controller as a module by switching it to a platform driver.
