The DMA API generally relies on a struct device to work properly, and
only barely works without one for legacy reasons. Pass the easily
available struct device from the platform_device to remedy this.

[ 36.950747] ret_from_fork+0x10/0x1c
I isolated this down to in ffs_epfile_io():
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/drivers/usb/gadget/function/f_fs.c#n1065
Where the completion done is setup on the stack:
DECLARE_COMPLETION_ONSTACK(done);
Then later we setup a request and queue it, and wait for it:
if (unlikely(wait_for_completion_interruptible(&done))) {
/*
* To avoid race condition with ffs_epfile_io_complete,
* dequeue the request first then check
* status. usb_ep_dequeue API should guarantee no race
* condition with req->complete callback.
*/
usb_ep_dequeue(ep->ep, req);
interrupted = ep->status < 0;
}
The problem is, that we end up being interrupted, dequeue the
request, and exit.
But then the irq triggers and we try calling complete() on the
context pointer which points to now random stack space, which
results in the panic.
Alan Stern pointed out there is a bug here, in that the snippet
above "assumes that usb_ep_dequeue() waits until the request has
been completed." And that:
wait_for_completion(&done);
Is needed right after the usb_ep_dequeue().
Thus this patch implements that change. With it I no longer see
the crashes on suspend or reboot.
This issue seems to have been uncovered by behavioral changes in
the dwc3 driver in commit fec9095bdef4e ("usb: dwc3: gadget:
remove wait_end_transfer").

This patch adds support for transferring requests, which are
non-contiguous in physical memory, i.e. the data buffer is described by
a scatter-list. This allows transferring large requests without relying
on error-prone contiguous buffer allocations. This way of allocating
requests is already implemented in functionfs and TCM USB functions and
automatically used if UDC driver advertises scatter-gather suppport.

A reset e.g. calling ep_reset_338x() can happen while endpoints
are enabled. The ep_reset_338x() sets ep->desc = NULL to mark
endpoint being invalid. A subsequent call of net2280_disable will
fail and return -EINVAL to parent function usb_ep_disable(),
which will fail, too, and do not set the member ep->enabled = false.
See:
https://elixir.bootlin.com/linux/v5.0-rc5/source/drivers/usb/gadget/udc/core.c#L139
This fix ignores dp->desc and allows net2280_disable() to succeed.
Subsequent calls to usb_ep_enable()/usb_ep_disable() succeeds.

Commit bf594c1070f5 ("USB: gadget: Document that certain ep operations
can be called in interrupt context") documented that usb_ep_dequeue()
may be called in a non-process context. It follows that the routine
must not sleep or wait for events.
However, the routine's existing kerneldoc seems to imply that it will
wait until the request being cancelled has fully completed. This is
not so, and thus the comment needs to be improved. Misunderstanding
this point may very well have been responsible for a bug recently
uncovered in the f_fs function.
The updated comment explicitly says that the routine may return before
the request's completion handler is called.

There is a rare race condition that may happen during a Disconnect
Interrupt if we have a started request that happens to be
dequeued *after* completion of End Transfer command. If that happens,
that request will be left waiting for completion of an End Transfer
command that will never happen.
If End Transfer command has already completed before, we are safe to
giveback the request straight away.

On v3.10a in dual-role mode, if port is in device mode
and gadget driver isn't loaded, the OTG event interrupts don't
come through.
It seems that if the core is configured to be OTG2.0 only,
then we can't leave the DCFG.DEVSPD at Super-speed (default)
if we expect OTG to work properly. It must be set to High-speed.
Fix this issue by configuring DCFG.DEVSPD to the supported
maximum speed at gadget init. Device tree still needs to provide
correct supported maximum speed for this to work.
This issue wasn't present on v2.40a but is seen on v3.10a.
It doesn't cause any side effects on v2.40a.
