I posted it as part of a 2 patch series [1]. In addition, Joe Perches noticed I forgot 3 instances of debugfs_create_file() in core.c so I was about to fix that in v5 of the patch series. v5 is mostly addressing comments on the pinmux-select feature. Thank you, Drew [1] https://lore.kernel.org/linux-gpio/20210210222851.232374-1-drew@beagleboard.org/

Oh I saw that and pulled it out again, no big deal. Yours, Linus Walleij

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. drivers/pinctrl/core.c | 6 +++--- drivers/pinctrl/pinconf.c | 4 ++-- drivers/pinctrl/pinmux.c | 4 ++-- 3 files changed, 7 insertions(+), 7 deletions(-)
