The way our code was written, we should never have
a DWC3_EP_PENDING_REQUEST flag set out of a Data Phase
and the code in __dwc3_gadget_ep0_queue() did not
reflect that situation properly.
Tidy up that case to avoid any possible mistakes
when starting requests for IRQs which are long
gone.

Currently rx aggregation related states are maintained per
vif, but this will not properly work when operating in AP mode.
Aggregation is completely broken when more than one
11n stations are connected to AP mode vif. Fix this issue
by keeping station specific aggregation state in sta_list.

The tid which is given in addba/delba req event is not
just tid but also muxed with the assoc id (MSB 4 bits)
which can be used to determine the corresponding connected
station in softap mode. The actual tid is LSB 4 bits. Using
the tid as it is with rx_tid[] would result in OOB or invalid
memory access in AP mode.

This patch just groups connection specific aggregation information

In wm2000_i2c_probe(), if we take the true branch in
"
ret = snd_soc_register_codec(&i2c->dev, &soc_codec_dev_wm2000,
NULL, 0);
if (ret != 0)
goto err_fw;
"
then we'll release_firmware(fw) at the 'err_fw' label. But we've already
done that just a few lines above. That's a use-after-free bug.
This patch restructures the code so that we always call
release_firmware(fw) before leaving the function, but only ever call
it once.
This means that we have to initialize 'fw' to NULL since some paths
may now end up calling it without having called request_firmware(),
but since request_firmware() deals gracefully with NULL pointers, we
are fine if we just NULL initialize it.

musb_shutdown() does pm_runtime_get_sync/pm_runtime_put by itself, so

dummy_hcd provides (alloc|free)_stream() callbacks but there are not
doing anything. The transfer side also lacks matching of streams. This
patch changes this and implements stream allocation / de-allocation
support and proper urb <=> req matching.
The UDC side exposes a limit of 16 streams. DWC3, the only USB3 UDC has
no limitations in this regard except that it _needs_ to know that
streams will be used at the ep_enable time. At the host side, there is
no real limit either: XHCI can allocate any number of streams as long as
it does not run out of memory. The UAS gadget currently requests 16
streams and the UAS host side fallbacks from the requested 256 down to
16 which is fine.
From the UASP point of view (the only specified user), the number of
used streams does not really matter. The only limitation is that the
host may not use a higher stream than the gadget requested and can deal
with.
The dummy stream support has been modelled after current UAS + XHCI +
DWC3 + UASP usage which helps me testing:
- the device announces that each ep supports 16 streams (even it could
more than that).
- the device side looks into Companion descriptor at ep_enable time and
enables them according to it.
- the host side tries to enable the requested number of streams but the
upper limit is the Comanion descriptor. None (zero streams) is an
error condition, less is okay.

While playing with uasp I noticed that it does not work with dummy_hcd.
The problem is that uasp requires a stream capable endpoint which it is
requesting at bind time like every other gadget. dummy_hcd however
initializes the max_stream value after connect once it knows if it runs
at SS or not.
I don't think that it is might be wrong to initialize the stream
capability even at HS speed. The gadget may not use this descriptor at
HS speed so it should not cause any damage.

ioremap() has become more picky and is now spitting out console messages like:

a couple of data structures that the EINJ table points to. Perhaps
acpi_os_map_memory() is a better tool for this?
Most importantly it works, but as a side benefit it maps the structures
into kernel virtual space so we can access them with normal C memory

we can use the more natural:
