Some USB controllers have common resources (IRQ, register address
space) for Host, Peripheral and OTG. So HCD is added only before
entering into Host mode. Root hub initialization is done in
different steps to decrease boot up time. But this makes B-device
difficult to meet HNP timings. Hence eliminate delays involved in
root hub initialization for B-host.
This patch also marks hnp_supported flag TRUE for B-host while
registering the bus.

Parens here are not necessary.
there's also a missing space before &&
That's my Thunderbird eating spaces before &. :-)
