From 2c21fd53a1a0ab8cf0438a9d554ad47d1e9704b2 Mon Sep 17 00:00:00 2001 From: Li Zetao Date: Tue, 10 Sep 2024 23:48:03 +0800 Subject: media: siano: remove redundant null pointer checks in cec_devnode_init() Since the debugfs_create_dir() never returns a null pointer, checking the return value for a null pointer is redundant, Remove this check since debugfs_create_file can handle IS_ERR pointers.
