[PATCH] platform/x86:intel/pmc: Update Arrow Lake telemetry GUID
Posted by Xi Pardee 5 months, 3 weeks ago 
Updated ARL_PMT_DMU_GUID value. Arrow Lake PMT DMU GUID has
been updated after it was released. This updates ensures that
the die c6 value is available in the debug filesystem.

Fixes: 83f168a1a437 ("platform/x86/intel/pmc: Add Arrow Lake S support to intel_pmc_core driver")
