GPU/i915: Fix acpi_bus_get_device() check in
drivers/gpu/drm/i915/intel_opregion.c
Bug detailed description:
--------------------------------------------
Fbset will cause calltrace. And I found that only happened at kernel with
kernel hijack options. If I disable the kernel hijack options, then build
kernel and redo fbset, calltrace will not happen. Bisect is on the way, I will
paste the first commit info later.
Reproduce steps:
--------------------------------------------
1. reboot or start
2. fbset -xres 800 -yres 600</pre>
