Why do you remove it, without adding it somewhere else. Nothing in the
commit msg explains it.

Why qusb2_phy is after hs_phy_irq? In the earlier if:then: it is the

Hm, why? This commit is unmanageable. Your commit msg is already huge
but still does not explain this. Are you sure you are fixing only one
logical thing per patch? Does not look like.
