Since commit b69578df7e ("USB: usbserial: mos7720: add support for
parallel port on moschip 7715"), the interrupt urb is no longer
submitted at first port open and the endpoint-address initialisation at
port-probe is no longer used.
Signed-off-by: Johan Hovold <johan@kernel.org>
A static usb-serial-driver structure that is used to initialise the
interrupt URB was modified during probe depending on the currently
probed device type, something which could break a parallel probe of a
device of a different type.
Fix this up by overriding the default completion callback for MCS7715
devices in attach() instead. We may want to use two usb-serial driver
instances for the two types later.

ktime is a union because the initial implementation stored the time in
scalar nanoseconds on 64 bit machine and in a endianess optimized timespec
variant for 32bit machines. The Y2038 cleanup removed the timespec variant
and switched everything to scalar nanoseconds. The union remained, but
become completely pointless.
Get rid of the union and just keep ktime_t as simple typedef of type s64.

USB controller type "mtu3", a new usb-serial driver, and the usual
churn in the gadget subsystem and the xhci host controller driver,
along with a few other new small drivers added. And lots of little
other changes all over the USB and PHY driver tree. Full details are
in the shortlog
All of these have been in linux-next for a while with no reported
issues"

This patch adds support for PIDs 0x1040, 0x1041 of Telit LE922A.
Since the interface positions are the same than the ones used
for other Telit compositions, previous defined blacklists are used.

copy_from_iter_full(), copy_from_iter_full_nocache() and
csum_and_copy_from_iter_full() - counterparts of copy_from_iter()
et.al., advancing iterator only in case of successful full copy
and returning whether it had been successful or not.
Convert some obvious users. *NOTE* - do not blindly assume that
something is a good candidate for those unless you are sure that
not advancing iov_iter in failure case is the right thing in
this case. Anything that does short read/short write kind of
stuff (or is in a loop, etc.) is unlikely to be a good one.

The ohci_hcd_pxa27x_drv_probe function is not doing anything other
than calling usb_hcd_pxa27x_probe function so ohci_hcd_pxa27x_drv_probe
function is useless that is why removed ohci_hcd_pxa27x_drv_probe
function and renamed usb_hcd_pxa27x_probe function to
ohci_hcd_pxa27x_drv_probe for proper naming.
The ohci_hcd_pxa27x_remove function is also not doing anything other than
calling usb_hcd_pxa27x_remove that is why removed ohci_hcd_pxa27x_remove
function and renamed usb_hcd_pxa27x_remove to ohci_hcd_pxa27x_remove for
proper naming.

The ohci_hcd_omap_drv_probe and ohci_hcd_omap_drv_remove
functions are removed as these are useless functions except calling
usb_hcd_omap_probe and usb_hcd_omap_remove functions.
The usb_hcd_omap_probe function renamed to ohci_hcd_omap_probe
and usb_hcd_omap_remove function renamed to ohci_hcd_omap_remove
for proper naming.
