From fa46d2873c9fa4060ce407e4bc5c7e29babce9d0 Mon Sep 17 00:00:00 2001 From: Mario Limonciello Date: Sat, 12 Oct 2024 12:45:19 -0500 Subject: cpufreq/amd-pstate: Drop needless EPP initialization The EPP value doesn't need to be cached to the CPPC request in amd_pstate_epp_update_limit() because it's passed as an argument at the end to amd_pstate_set_epp() and stored at that time.
