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

I guess it also needs Suggested-by: Joe (IIRC he proposed to convert the rest).

Sorry for the confusion.

"[PATCH v8 0/3] pinctrl: pinmux: Add pinmux-select debugfs file" [1]
sent Feb. 20th was in my opinion ready to merge.

However, it occured to me yesterday since there had been no replies to
that thread, then it might be a good idea to add a 4th patch to rename
pinctl.rst to pin-control.rst. I sent that yesterday as v9 [2] but I am
fine with that being dropped as renaming pinctl.rst is unrelated to my 
actual goal of adding pinmux-select to debugfs.

thanks,
drew
