From: Mario Limonciello Date: Fri, 27 Jun 2025 14:34:30 +0000 (-0500) Subject: drm/amd: Decrease message level for legacy-pm, kv-dpm and si-dpm X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=de5e9fe092f90b913de881fe05e6aa8e90f97184;p=thirdparty%2Flinux.git drm/amd: Decrease message level for legacy-pm, kv-dpm and si-dpm legacy-pm, kv-dpm and si-dpm have prints while changing power states that don't have a level and thus are printed by default. These are not useful at runtime for most people, so decrease them to debug.
