From 929f265c40feadfd57e3a8c650a007b541fde2b1 Mon Sep 17 00:00:00 2001 From: Jiasheng Jiang Date: Thu, 26 May 2022 17:03:45 +0800 Subject: [PATCH] platform/x86: barco-p50-gpio: Add check for platform_driver_register [ Upstream commit 011881b80ebe773914b59905bce0f5e0ef93e7ba ] As platform_driver_register() could fail, it should be better to deal with the return value in order to maintain the code consisitency.
