Subject: [PATCH] drm/i915/gt: Define guc firmware blob for older Cometlakes
Git-commit: 557862535c2cad6de6f6fb12312b7a6d09c06407
Patch-mainline: v5.11-rc3
No-fix: 70960ab27542d8dc322f909f516391f331fbd3f1
References: git-fixes
When splitting the Coffeelake define to also identify Cometlakes, I
missed the double fw_def for Coffeelake. That is only newer Cometlakes
use the cml specific guc firmware, older Cometlakes should use kbl
firmware.
