Feel free to send an additional cleanup patch ... otherwise, I'd say let
it bitrot for another year and we then remove it completely together
with all the other "-usbdevice" functions...

Just the two exotic parameters. But I agree with Gerd: If you google for
the option to see how people are using the usbdevice option, you almost
only find pages that describe "-usbdevice mouse/keyboard/tablet" or host
passthrough. Sometimes also "storage". But hardly anything about
"serial". However, I've now also found a bug where someone complains
about the vendorid/productid problem:
https://bugs.launchpad.net/qemu/+bug/1180924
So that's an indication that at least some few people used "-usbdevice
serial" in the past ... so let's fix that coverity warning now instead,
then add some proper deprecation warnings to the "-usbdevice" parameter
and remove all that legacy stuff next year...

All breanches of the "if" now return NULL, so the "while" loop in turn
can become an
if (*filename && *filename != ':') {
}
and the "while (*filename == ',')" subloop can go away, replaced by just
"return NULL".
Even better, the "if (!*filename)" if just below can be moved first.

Being broken counts as being deprecated, I'd say.
But was -usbdevice serial broken? Or just its two optional (and
somewhat exotic) parameters?

It will be clean once removed, I likewise wouldn't put too much effort into code which is scheduled for removal anyway, especially for more or less cosmetic issues like unreachable code. > Hmm, maybe we should simply remove "-usbdevice serial" right now already > ... ?

Hmm, there is little reason to set vendorid + productid, so that alone is no strong indication that -usbdevice serial is unused. But nevertheless I think it usb-serial is one of the rarely used devices, so we could try ... Order is probably along these lines: usb hid devices are used alot (tablet on x86, all on !x86). usb-storage comes next I guess. usb-host (aka pass-through) is important too of course. Everything else (serial, net, bluetooth) is largely unused I guess. ccid, uas and mtp are new enough to not carry around -usbdevice compatibility support. cheers, Gerd

Hmm, maybe we should simply remove "-usbdevice serial" right now already
... ? The vendorid/productid parameter handling has been broken since
QEMU v0.14 already and nobody ever complained, so I guess hardly anybody
is using "-usbdevice serial" anymore ... so I tend to simply remove it

wait-two-release-cycles -> finally-remove-it" process here...
Paolo, Gerd, what do you think?
