Make use of the struct_size() helper instead of an open-coded version
in order to avoid any potential type mistakes, in particular in the
context in which this code is being used.

So, change the following form:

sizeof(*packet_desc) + (sizeof(packet_desc->PacketLength[0]) * seg->isoc_frame_count)

to :

struct_size(packet_status, PacketStatus, seg->isoc_frame_count);

One of the more common cases of allocation size calculations is finding
the size of a structure that has a zero-sized array at the end, along
with memory for some number of elements for that array. For example:

struct foo {
    int stuff;
    struct boo entry[];
};

size = sizeof(struct foo) + count * sizeof(struct boo);
instance = kzalloc(size, GFP_KERNEL);

Instead of leaving these open-coded and prone to type mistakes, we can
now use the new struct_size() helper:

instance = kzalloc(struct_size(instance, entry, count), GFP_KERNEL);

Notice that, in this case, variable len is not necessary, hence
it is removed.

The return from the call to fwnode_property_read_u16_array is int,
it can be a negative error code however this is being assigned to

USB: changes for v5.1 merge window

Dwc3 now works on TI's AM6xx platforms. Also on dwc3 we have a few
changes which improve request cancellation and some improvements to
how we print to the trace buffer.

Renesas_usb3 got support for r8a774c0 device.

Dwc2 got scatter-gather support.

Apart from these, the usual set of minor fixes and all sorts of small

The new mux connection naming scheme is now in use, so
dropping the connections still using the old names. From now
on the same connection description named "mode-switch" is
used with both the port and the alternate modes, so on CHT
the DP alt mode will use the same connection as the port to
get a handle to the mux device.

Since with accessory modes there is no need for additional
identification when requesting a handle to the mux, we can
replace the second parameter that is passed to the
typec_mux_get() function with a pointer to alternate mode
description structure, and simply passing NULL with
accessory modes.

This change means the naming of the mux device connections
can be updated. Alternate and Accessory Modes will both be
handled with muxes named "mode-switch", and the orientation
switches will be named "orientation-switch".

Future identification of the alternate modes will be later
done using device property "svid" of the mux.

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 fec9095b ("usb: dwc3: gadget:
remove wait_end_transfer").
