[Nouveau] [PATCH] nouveau: Switch perms from macros to octal notations, module params readable to everyone
From: poma <pomidorabelisima at gmail.com>
Switch from "silly" S_* macros to "definitely more readable"
octal "way" permissions,
moreover to not "so restrictive" module parameters permissions.
Suggested-by: Ilia Mirkin <imirkin at alum.mit.edu>
Fixes: poma <pomidorabelisima at gmail.com>
Tested-by: poma <pomidorabelisima at gmail.com>
