From: Matt Roper Date: Wed, 2 Oct 2024 23:06:21 +0000 (-0700) Subject: drm/xe: Make wedged_mode debugfs writable X-Git-Tag: microblaze-v6.16~912^2^2 X-Git-Url: http://git.monstr.eu/?a=commitdiff_plain;h=1badf482816417dca71f8120b4c540cdc82aa03c;p=linux-2.6-microblaze.git drm/xe: Make wedged_mode debugfs writable 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.
