Subject: [PATCH] pinctrl: use to octal permissions for debugfs files
Date: Mon, 25 Jan 2021 20:47:43 -0800	[thread overview]
Message-ID: <20210126044742.87602-1-drew@beagleboard.org> (raw)

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").

Signed-off-by: Drew Fustini <drew@beagleboard.org>

Patch note:
- I learned about this preference of octal over symbolic when I created
  an RFC to add a new debugfs file ("pinmux-select"). I am submitting
  this patch to switch existing entries in pinctrl over to octal before
  I submit a proper PATCH for the "pinmux-select" functionality in which
  I will use octal permissions for the new file.
