drm/i915/huc: Avoid attempting to authenticate non-existent fw
HuC authentication is called even if HuC firmware is not present in the system, leading to NULL ptr dereference on not allocated gem_object. Let's avoid trying to authenticate HuC if its firmware is not loaded successfully. Fixes: dac84a38 ("drm/i915/huc: Support HuC authentication") v2: Check inside the auth function, split the assert (Michał) v3: Oops, hit send before compiling, s/huc_fw/huc->fw Cc: Anusha Srivatsa <anusha.srivatsa@intel.com> Cc: Arkadiusz Hiler <arkadiusz.hiler@intel.com> Cc: Chris Wilson <chris@chris-wilson.co.uk> Reviewed-by:Michal Wajdeczko <michal.wajdeczko@intel.com> Signed-off-by:
