From: Noralf Trønnes Date: Thu, 26 Jan 2017 22:56:11 +0000 (+0100) Subject: drm/msm: Remove drm_debugfs_remove_files() calls X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=81895b54093af47549d572608677c624972055da;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git drm/msm: Remove drm_debugfs_remove_files() calls drm_debugfs_cleanup() now removes all minor->debugfs_list entries automatically, so it's not necessary to call drm_debugfs_remove_files(). Additionally it uses debugfs_remove_recursive() to clean up the debugfs files, so no need to do that.
