I tested 1/3 and 2/3 on 3.13 kernel. And as expected (because patches doing
same thing) same result as with my patch - no kernel crash anymore. You can add
my Signed-off.

I do not have nvidia optimus card, so I cannot test last patch.

Anyway in vga_switcheroo.c is exported function
vga_switcheroo_init_domain_pm_optimus_hdmi_audio() which changing
dev->pm_domain too. But I do not see any driver which using it.
