Subject: drm/i915/uc: Reorder firmware status codes
Git-commit: 3243bd096bb1656dfab7a1f3699d4d94692fd14c
Patch-mainline: v5.4-rc1
References: bsc#1152489
On Gen9 when we try to reload HuC due to GuC upload error, we hit:
<7> [232.025927] [drm:intel_uc_init_hw [i915]] GuC fw load failed: -8; will reset and retry 2 more time(s)
<7> [232.026004] [drm:intel_uc_fw_upload [i915]] HuC fw load i915/kbl_huc_ver02_00_1810.bin
<7> [232.026686] [drm:intel_uc_fw_upload [i915]] HuC fw xfer completed
<6> [232.026688] [drm] HuC: Loaded firmware i915/kbl_huc_ver02_00_1810.bin (version 2.0)
<3> [232.026703] intel_uc_fw_copy_rsa:541 GEM_BUG_ON(!intel_uc_fw_is_available(uc_fw))
as firmware that previously failed to load was wrongly treated as
unavailable since its status code was not matching status check logic.
