From ac2f033aa4fbc94a512e703a953ed36e1bb45d0a Mon Sep 17 00:00:00 2001 From: Xiaomeng Tong Date: Wed, 13 Apr 2022 13:11:05 +0800 Subject: [PATCH] drm/gma500: fix a potential repeat execution in psb_driver_load Instead of exiting the loop as expected when an entry is found, the list_for_each_entry() continues until the traversal is complete. To avoid potential executing 'ret = gma_backlight_init(dev);' repeatly, goto outside the loop when found entry by replacing switch/case with if statement.
