[PATCH 1/2] drm/debugfs: use octal permissions instead of symbolic permissions

From: Maíra Canal
Date: Thu Jan 05 2023 - 14:34:06 EST


Currently, debugfs functions are using symbolic macros as permission
bits, but checkpatch reinforces permission bits in the octal form, as
they are more readable and easier to understand [1].

Therefore, use octal permission bits in all debugfs functions.
