The "write backlight harder" patch causes black screen after suspend on my HP
Pavilion dv6-6179er. If I revert it, everything works fine. Also, setting
backlight level twice, but without "if (!intel_panel_get_backlight(dev))" works
fine too. I even inserted a printk before this if, and it reports:
[   68.335727] i915 backlight: 4882
which is max backlight level.
