Looks like pm_runtime_disable() got dropped from your 36d48fb5766a 
("i2c: designware-platdrv: enable RuntimePM before registering to the 
core") while handling the merge conflict. I'll send a fix.

I'll have a look at it. What's not entirely clear to me would it be 
no-op or not. HW is actually disabled after i2c_dw_init() which is 
called before requesting the interrupt but is not clear to me from the 
spec does HW clear interrupts while it goes idle.

So as a result I'd expect either a explicit interrupt clearing patch (to 
be more robust against potential unmasking changes) or a comment in 
__i2c_dw_enable() :-)
