Subject: [PATCH] drm/amdgpu: Fix build with missing pm_suspend_target_state module export
Date: Tue, 24 Aug 2021 11:42:47 +0200	[thread overview]
Message-ID: <YSS/F9kcQcRKlNJ5@zn.tnic> (raw)
In-Reply-To: <CADnq5_N0q8Rfm++O3jK6wcbePxg_Oj3=Xx9Utw60npKrEsSp8A@mail.gmail.com>

From: Borislav Petkov <bp@suse.de>

Building a randconfig here triggered:

  ERROR: modpost: "pm_suspend_target_state" [drivers/gpu/drm/amd/amdgpu/amdgpu.ko] undefined!

because the module export of that symbol happens in
kernel/power/suspend.c which is enabled with CONFIG_SUSPEND.

The ifdef guards in amdgpu_acpi_is_s0ix_supported(), however, test for
CONFIG_PM_SLEEP which is defined like this:

  config PM_SLEEP
          def_bool y
          depends on SUSPEND || HIBERNATE_CALLBACKS

and that randconfig has:

  # CONFIG_SUSPEND is not set
  CONFIG_HIBERNATE_CALLBACKS=y

leading to the module export missing.

Change the ifdeffery to depend directly on CONFIG_SUSPEND.

Fixes: 5706cb3c910c ("drm/amdgpu: fix checking pmops when PM_SLEEP is not enabled")
