USB: serial: stop reporting legacy UART types
The TIOCGSERIAL ioctl can be used to set and retrieve the UART type for legacy UARTs, but some USB serial drivers have been reporting back random types in order to "make user-space happy".
Some applications have historically expected TIOCGSERIAL to be implemented, but judging from the Debian sources, the port type not being PORT_UNKNOWN is only used to check for the existence of legacy serial ports (ttySn).
Drivers like ftdi_sio have been using PORT_UNKNOWN for twenty years (and option for 10 years) without anyone complaining so let's stop reporting back anything else.
In the unlikely event that this do cause problems, this should be fixed tree-wide anyway (e.g. for all USB serial drivers and also CDC-ACM).

USB: serial: add generic support for TIOCSSERIAL
TIOCSSERIAL is a horrid, underspecified, legacy interface which for most serial devices is only useful for setting the close_delay and closing_wait parameters.
The closing_wait parameter determines how long to wait for the transfer buffers to drain during close and the default timeout of 30 seconds may not be sufficient at low line speeds. In other cases, when for example flow is stopped, the default timeout may instead be too long.
Add generic support for TIOCSSERIAL and TIOCGSERIAL with handling of the three common parameters close_delay, closing_wait and line for the benefit of all USB serial drivers while still allowing drivers to implement further functionality through the existing callbacks.
This currently includes a few drivers that report their base baud clock rate even if that is really only of interest when setting custom divisors through the deprecated ASYNC_SPD_CUST interface; an interface which only the FTDI driver actually implements.
Some drivers have also been reporting back a fake UART type, something which should no longer be needed and will be dropped by a follow-on patch.

USB: serial: opticon: fix TIOCGSERIAL implementation
TIOCSSERIAL is a horrid, underspecified, legacy interface which for most serial devices is only useful for setting the close_delay and closing_wait parameters.
The xmit_fifo_size parameter could be used to set the hardware transmit fifo size of a legacy UART when it could not be detected, but the interface is limited to eight bits and should be left unset when not used.
Similarly, baud_base could be used to set the UART base clock when it could not be detected but might as well be left unset when it is not known.
The close_delay and closing_wait parameters returned by TIOCGSERIAL are specified in centiseconds (not jiffies). The driver does not yet support changing these, but let's report back the default values actually used (0.5 and 30 seconds, respectively).

USB: serial: Remove redundant license text
Now that the SPDX tag is in all USB files, that identifies the license in a specific and legally-defined manner. So the extra GPL text wording can be removed as it is no longer needed at all.
This is done on a quest to remove the 700+ different ways that files in the kernel describe the GPL license text. And there's unneeded stuff like the address (sometimes incorrect) for the FSF which is never needed.
No copyright headers or other non-license-description text was removed.

It's good to have SPDX identifiers in all files to make it easier to audit the kernel tree for correct licenses.
Update the drivers/usb/ and include/linux/usb* files with the correct SPDX license identifier based on the license text in the file itself. The SPDX identifier is a legally binding shorthand, which can be used instead of the full boiler plate text.
This work is based on a script and data from Thomas Gleixner, Philippe Ombredanne, and Kate Stewart.

USB: serial: opticon: fix CTS retrieval at open
The opticon driver used a control request at open to trigger a CTS status notification to be sent over the bulk-in pipe. When the driver was converted to using the generic read implementation, an inverted test prevented this request from being sent, something which could lead to TIOCMGET reporting an incorrect CTS state.

USB: serial: make minor allocation dynamic
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.

USB: serial: ports: add minor and port number
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.
