Yes, this line:
*ERROR* Failed to fetch HuC firmware from i915/skl_huc_ver01_07_1398.bin
means that it failed to find the firmware.
If you are using the HuC (only require for some extra media codecs) then
you may need to update libraries as well as installing the firmware. If
you are just testing the patches then you can just ignore this error.

Do you have the firmware package for the SKL huc?
Sorry, no, is this error log due to lack of the firmware?
Thanks,
