Gustavo has been working to fix up all of the switch statements that
"fall through" such that we can eventually turn on
-Wimplicit-fallthrough. As part of that, the io_edgeport.c driver is a
bit "messy" with the parsing logic of a data packet. Clean that logic
up a bit by unindenting one level of the logic, and properly label
/* Fall through */ to make gcc happy.

The USB completion callback does not disable interrupts while acquiring
the lock. We want to remove the local_irq_disable() invocation from
__usb_hcd_giveback_urb() and therefore it is required for the callback
handler to disable the interrupts while acquiring the lock.
The callback may be invoked either in IRQ or BH context depending on the
USB host controller.
Use the _irqsave() variant of the locking primitives.

process_rcvd_data
process_rcvd_status

This moves the allocation of minor device numbers from a static array to
be dynamic, using the idr interface. This means that you could
potentially get "gaps" in a minor number range for a single USB serial
device with multiple ports, but all should still work properly.
We remove the 'minor' field from the usb_serial structure, as it no
longer makes any sense for it (use the field in the usb_serial_port
structure if you really want to know this number), and take the fact
that we were overloading a number in this field to determine if we had
initialized the minor numbers or not, and just use a flag variable
instead.
Note, we still have the limitation of 255 USB to serial devices in the
system, as that is all we are registering with the TTY layer at this
point in time.

The usb_serial_port structure had the number field, which was the minor
number for the port, which almost no one really cared about. They
really wanted the number of the port within the device, which you had to
subtract from the minor of the parent usb_serial_device structure. To
clean this up, provide the real minor number of the port, and the number
of the port within the serial device separately, as these numbers might
not be related in the future.
Bonus is that this cleans up a lot of logic in the drivers, and saves
lines overall.

module_param(bool) used to counter-intuitively take an int. In
fddd5201 (mid-2009) we allowed bool or int/unsigned int using a messy
trick.
It's time to remove the int/unsigned int option. For this version
it'll simply give a warning, but it'll break next kernel version.
