From a8dc0f6d187bcccc7c1a41f0062badbf3d74e44c Mon Sep 17 00:00:00 2001 From: Michal Wajdeczko Date: Sun, 18 Aug 2019 09:52:04 +0000 Subject: [PATCH] drm/i915/uc: Never fail on HuC firmware errors There is no need to mark whole GPU as wedged just because of the custom HuC fw failure as users can always verify actual HuC firmware status using existing HUC_STATUS ioctl.
