A git bisect just pointed me at commit d32932d02e18 ("x86/irq: Convert
IOAPIC to use hierarchical irqdomain interfaces") as the reason for why
the trackpad on my Dell XPS13 is no longer working with v4.2-rc1.

I'm now seeing the following errors when booting,

[    1.615017] i2c_designware INT3433:00: controller timed out
[    1.642496] i2c_designware INT3433:00: timeout in disabling adapter        
[    1.642500] i2c_hid i2c-DLL0665:01: hid_descr_cmd failed

I tried commit d32932d02e18~1, which works, and things definitely break
starting with commit d32932d02e18.

Any suggestions or requests to try and diagnose why the irqdomain
changes broke this i2c controller driver?
