[Nouveau] [PATCH] gpu: Consistently use octal not symbolic permissions
There is currently a mixture of octal and symbolic permissions uses
in files in drivers/gpu/drm and one file in drivers/gpu.
There are ~270 existing octal uses and ~115 S_<FOO> uses.
Convert all the S_<FOO> symbolic permissions to their octal equivalents
as using octal and not symbolic permissions is preferred by many as more
readable.
see: https://lkml.org/lkml/2016/8/2/1945
Done with automated conversion via:
$ ./scripts/checkpatch.pl -f --types=SYMBOLIC_PERMS --fix-inplace
<files...>
Miscellanea:
o Wrapped modified multi-line calls to a single line where appropriate
o Realign modified multi-line calls to open parenthesis
o drivers/gpu/drm/msm/adreno/a5xx_debugfs.c has a world-writeable
debug permission for "reset" - perhaps that should be modified

But you could do that via something like: $ git am --include='drivers/gpu/drm/i915/*' <patch> cheers, Joe
Apparently Analagous Threads
- [PATCH] gpu: Consistently use octal not symbolic permissions
- [PATCH v5 5/5] nouveau_hwmon: Change permissions to numeric
- [PATCH] drm/nouveau: remove checks for return value of debugfs functions
- [PATCH] nouveau: no need to check return value of debugfs_create functions
- [PATCH] nouveau: Switch perms from macros to octal notations, module params readable to everyone
