Ok. seems sane. Possibly it makes sense to add specific handling for all
those cases on the longer term, but not crashing seems like a good
feature for now :-)

You are right, I had placed the parenthesis wrong. I see what happens
there now, yes.

There were actually two sides to this part of the patch. One was fixing
the bug I thought I saw, but the other was to remove the handling of
DWC2_HC_XFER_URB_DEQUEUE from dwc2_hc_chhltd_intr_dma, since that
function is never called with that halt_status anymore (and having dead
code makes it confusing). Armed with the correct knowledge about those
nested ifs, I've removed this handling in the below patch, which makes
the code even simpler.

Your changes look sane, except for my question below.
I've got another patch in return, with the changes mentioned above
(still untested as well) applied on top of your patch. I've tested this
patch quickly (no more time this weekend) and it seems to work.

I've been testing with an Alcatel X060S 3g dongle, but I suspect that
the problem will occur with any 3G dongle that uses the "option" driver
(which I think is most of them). Just tested a Huawei E173, which
triggers the same problem. Looking at the code, I think that other usb
serial devices might also trigger the problem. I just quickly tested a
PL2303 device, but that seems to trigger different problems, lots of:
[ 205.600000] dwc2 101c0000.otg: Unknown hub control request: 2308h wIndex: 1h wValue: 9031h
[ 205.620000] usb usb1: clear tt 1 (9031) error -22
which are probably unrelated (they appear with and without the patch),
but hide the problem. I suspect these are triggered by the fact that the
PL2303 is an USB1.1 device and the builtin transaction translator is
somehow not working properly (I had the same -22 error with a Huawei
E220 which is also USB1.1). I tried with an external hub, but the
debugging log from the split transactions receiving NAK replies kills my
CPU, so I couldn't reproduce it like this.
If you have any USB 2.0 serial device, you can probably try for yourself
by simply doing cat /dev/ttyUSB0 and then ^C'ing. Do this a few times
until you run out of host channels (which is only 4 on my hardware, so
this problem quickly becomes apparent).
I've attached a debug log which should also help illustrate the problem.
The first part is without the patch, you can see that when pressing ^C,
the urbs are dequeued but the last one is not released.
This works three times, but when running cat for the fourth time, the
channels are all taken up (one is used for an interrupt endpoint), so
urbs are queued, but never assigned a hc. With the patch, I can run cat
as much as I like, without keeping any channels occupied.

Why change this function? AFAICS it's never called with qtd = NULL with
the patch?

commit d991b329c35125abdfc571c9451406ed8ce20e80

staging: dwc2: Always release host channel after dequeueing
Previously, when an active urb was dequeued, its host channel would not
always be released. There is some special handling for this in
dwc2_hc_chhltd_intr_dma, but when it was the last urb/qtd in its qh, a
safeguard in dwc2_hc_n_intr would short-circuit and prevent the regular
interrupt handlers from running, without releasing the channel.
This is easily triggered when using a 3G modem using the option driver.
Opening and closing any ttyUSBx device will eat up a host channel that
is forever unusable from that point on.
