This error path needs to unwind instead of just returning directly.

MODULE_SUPPORTED_DEVICE was added in pre-git era and never was
implemented. We can safely remove it, because the kernel has grown
to have many more reliable mechanisms to determine if device is
supported or not.

Rationale:
Reduces attack surface on kernel devs opening the links for MITM
as HTTPS traffic is much harder to manipulate.
Deterministic algorithm:
For each file:
If not .svg:
For each line:
If doesn't contain `\bxmlns\b`:
For each link, `\bhttp://[^# \t\r\n]*(?:\w|/)`:
If neither `\bgnu\.org/license`, nor `\bmozilla\.org/MPL\b`:
If both the HTTP and HTTPS versions
return 200 OK and serve the same content:
Replace HTTP with HTTPS.

Now that the SPDX tag is in all tty 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/tty files 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.

There was an error on the jsm driver that would cause it to be unable to
recover after a second error is detected.
At the first error, the device recovers properly:
[72521.485691] EEH: Detected PCI bus error on device 0003:02:00.0
[72521.485695] EEH: This PCI device has failed 1 times in the last hour:
...
[72532.035693] ttyn3 at MMIO 0x0 (irq = 49) is a jsm
[72532.105689] jsm: Port 3 added
However, at the second error, it cascades until EEH disables the device:
[72631.229549] Call Trace:
...
[72641.725687] jsm: Port 3 added
[72641.725695] EEH: Detected PCI bus error on device 0003:02:00.0
[72641.725698] EEH: This PCI device has failed 3 times in the last hour:
It was caused because the PCI state was not being saved after the first
restore. Therefore, at the second recovery the PCI state would not be
restored.

We are cleaning up the issue that means module.h is omnipresent.
These tty users are the people who implictly are relying on that.
Fix up the real users to call out the include that they really need.
In the case of jsm_driver.c file, it had moduleparam.h but that
isn't enough and it needs the full module.h

jsm uses a write queue that copies from uart_core circular buffer. This
copying however has some bugs, like not wrapping the head counter. Since
this write queue is also a circular buffer, the consumer function is
ready to use the uart_core circular buffer directly.
This buggy copying function was making some bytes be dropped when
transmitting to a raw tty, doing something like this.

I saw a warning about ioremap from the jsm driver on a system which
looked like this:
resource map sanity check conflict: 0xe0200800 0xe02017ff 0xe0200800 0xe0200fff 0000:01:08.0
Turns out the warning is valid. The jsm driver has been asking to ioremap
0x1000 forever, but in fact only 8 port chips have 0x1000 bytes of memory.
4 port chips have 0x800 and 2 port chips have 0x400 according to the
data sheet. It makes more sense to map the size of the region rather
than a hard coded value. If you happen to have the region legitimately
mapped to a base address that is not 4K aligned, ioremap complains
otherwise.

The serial drivers are really just tty drivers, so move them to
drivers/tty/ to make things a bit neater overall.
This is part of the tty/serial driver movement proceedure as proposed by
Arnd Bergmann and approved by everyone involved a number of months ago.
