[PATCH] drm/xe: Make wedged_mode debugfs writable

[Gustavo Sousa]

Quoting Matt Roper (2024-10-02 20:06:21-03:00)
>The intent of this debugfs entry is to allow modification of wedging
>behavior, either from IGT tests or during manual debug; it should be
>marked as writable to properly reflect this.  In practice this hasn't
>caused a problem because we always access wedged_mode as root, which
>ignores file permissions, but it's still misleading to have the entry
>incorrectly marked as RO.
