Subject: [PATCH v9 1/4] pinctrl: use to octal permissions for debugfs files
Date:   Mon,  1 Mar 2021 21:30:56 -0800
Message-Id: <20210302053059.1049035-2-drew@beagleboard.org>
In-Reply-To: <20210302053059.1049035-1-drew@beagleboard.org>

Switch over pinctrl debugfs files to use octal permissions as they are
preferred over symbolic permissions. Refer to commit f90774e1fd27
("checkpatch: look for symbolic permissions and suggest octal instead").

Note: S_IFREG flag is added to the mode by __debugfs_create_file()
in fs/debugfs/inode.c
