From: Borislav Petkov <b...@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")
