From a6cfa4c8833944f8912c1fa7f95795753f6376ea Mon Sep 17 00:00:00 2001 From: Mario Limonciello Date: Sat, 12 Jul 2025 18:37:12 -0500 Subject: [PATCH] PM: hibernate: Add stub for pm_hibernate_is_recovering() Randy reports that amdgpu fails to compile with the following error: ERROR: modpost: "pm_hibernate_is_recovering" [drivers/gpu/drm/amd/amdgpu/amdgpu.ko] undefined! This happens because pm_hibernate_is_recovering() is only compiled when CONFIG_PM_SLEEP is set. Add a stub for it so that drivers don't need to depend upon CONFIG_PM.
