Unfortunately I'm seeing interrupt storm during suspend/resume on 
platform using PM domain from drivers/acpi/acpi_lpss.c straight after 
this patch. Maybe some timing related as I see it only if I have debug 
messages on (i2c_designware_core.dyndbg=+p). But it occurs only after 
this patch.

Have to dig more deeply next week.
