From: Jinjie Ruan Date: Sat, 7 Oct 2023 08:43:39 +0000 (+0800) Subject: media: aspeed: Drop unnecessary error check for debugfs_create_file() X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=32ec99f872aba071a070f61fcab2f3a068b50652;p=linux.git media: aspeed: Drop unnecessary error check for debugfs_create_file() debugfs_create_file() return ERR_PTR and never return NULL. When calling debugfs functions, there is no need to ever check the return value. The function can work or not, but the code logic should never do something different based on this.
