The amdgpu_display_suspend_helper() function uses an uninitialized
variable as its return value, causing a failure to suspend/resume on a
Radeon R7 240/340 GPU, with the following error in dmesg:
[drm:amdgpu_device_ip_suspend_phase1 [amdgpu]] *ERROR* suspend of IP block <dce_v6_0> failed 118489088
Initialize the variable to 0.
