[PATCH] platform/x86/intel/pmc: initialize empty PMT read result
From: Yousef Alhouseen
Date: Tue Jun 30 2026 - 07:04:31 EST
pmc_core_pmt_get_lpm_req() returns the last telemetry read status. When
firmware exposes no enabled low-power modes, the loop does not run
and the function returns an uninitialized stack value.
Initialize the status to success so an empty mode set is handled
deterministically.
