From dbda45933684f8420f26a37b385e0f9d0b0857cb Mon Sep 17 00:00:00 2001 From: Mario Limonciello Date: Thu, 9 Dec 2021 12:13:53 -0600 Subject: [PATCH] drm/amd/pm: fix reading SMU FW version from amdgpu_firmware_info on YC This value does not get cached into adev->pm.fw_version during startup for smu13 like it does for other SMU like smu12.
