Subject: [PATCH] drm/i915/uc: Remove redundant GuC support checks
Git-commit: 34f0a20fa4ea8ad08b2d1fd43fa6e2febb9a4eff
Patch-mainline: v5.4-rc1
References: jsc#SLE-7953
Since commit db81bc6eb9c0 ("drm/i915/uc: Consider enable_guc
modparam during fw selection") we have started using firmware
status as main indicator of the GuC support. No need to use
same checks twice.
