commit eb132ccbdec5df46e29c9814adf76075ce83576b upstream.

Function-specific setup requests should be handled in such a way, that
apart from filling in the data buffer, the requests are also actually
enqueued: if function-specific setup is called from composte_setup(),
the "usb_ep_queue()" block of code in composite_setup() is skipped.

The printer function lacks this part and it results in e.g. get device id
requests failing: the host expects some response, the device prepares it
but does not equeue it for sending to the host, so the host finally asserts
timeout.

This patch adds enqueueing the prepared responses.

commit 7a606ac29752a3e571b83f9b3fceb1eaa1d37781 upstream.

While this driver was already using a 50ms resume
timeout, let's make sure everybody uses the same
macro so it's easy to fix later should anything
go wrong.

It also gives a more "stable" expectation to Linux
users.

commit 869aee0f31429fa9d94d5aef539602b73ae0cf4b upstream.

The res parameter passed to devm_usb_phy_match() is the location where the
pointer to the usb_phy is stored, hence it needs to be dereferenced before
comparing to the match data in order to find the correct match.
