[PATCH] sound: usb: mixer: increase control transfer timeout

[Felipe Balbi]

100ms might not be enough for slower devices. Increasing
timeout to 1000ms doesn't seem like overkill.

Not sure this information is valid on a commit log, but I
have a FPGA-platform which I use to test my USB controller
and when that's running on FS, this message fails because
control message times out before controller has the opportunity
to complete all three phases of the SETUP transaction.

Does it still happen if you remove all the debug output from your udc
driver?

I can try it out, but what's the point ? If we don't increase the
timeout, then whenever we want to debug some other problem, we will have
to keep a local patch on that file ?

If the timeout for reading values needs to be increased, writing (in
snd_usb_mixer_set_ctl_value) probably needs some attention too.

Ok, I'll increase all 100ms delays to 1000. Is that ok ?

How about also converting to use a local define for timeout value ?

Can't speak for maintainers, but personally I'd prefer a single patch with two
points in changelog. The change is trivial enough.

The calls in mixer_quirks.c are device-specific and known to work, so
none of them actually require a longer timeout. However, increasing
their timeout doesn't hurt either, and ...

... now that _all_ calls to snd_usb_ctl_msg use the same timeout value,
we could just as well drop this parameter.
