From 5be57099d44550d2c4cf44a86c44df87edb79a57 Mon Sep 17 00:00:00 2001 From: Saravana Kannan Date: Fri, 17 Jul 2020 17:06:35 -0700 Subject: [PATCH] irqchip/qcom-pdc: Switch to using IRQCHIP_PLATFORM_DRIVER helper macros Switch the driver to use the helper macros. In addition to reducing the number of lines, this also adds module unload protection (if the driver is compiled as a module) by switching from module_platform_driver to builtin_platform_driver.
