restoring backlight brightness sometimes delayed when returning from suspend

Submitted by Christian Hergert Link to original bug (#775729)
Description
Sometimes when returning from suspend, it takes about 15-30 seconds for my brightness to be restored. Trying to manually set it using the status menu from gnome-shell also does not work (and its really hard to see the menu without a backlight).
The brightness appears to be equal to the lowest setting on my Lenovo X1 Carbon Gen3. I'm running an up to date Fedora 25, and currently on Xorg. I haven't noticed this behavior on Wayland sessions, but that doesn't mean it's not possible there too. It doesn't happen every time.
I also think the unlock screen was very dim (having a hard time remembering) but I'm so used to typing that quickly that it probably was dim too.
