    drm/amdgpu: restore proper ref count in amdgpu_display_crtc_set_config · 3514521c
    Jean Delvare authored
    A recent attempt to fix a ref count leak in
    amdgpu_display_crtc_set_config() turned out to be doing too much and
    "fixed" an intended decrease as if it were a leak. Undo that part to
    restore the proper balance. This is the very nature of this function
    to increase or decrease the power reference count depending on the
    situation.
    
    Consequences of this bug is that the power reference would
    eventually get down to 0 while the display was still in use,
    resulting in that display switching off unexpectedly.
