The Documentation/DMA-API-HOWTO.txt states that the dma_map_sg() function
returns the number of the created entries in the DMA address space.
However the subsequent calls to the dma_sync_sg_for_{device,cpu}() and
dma_unmap_sg must be called with the original number of the entries
passed to the dma_

Upon running sparse, "warning: dubious: !x | !y" is brought to notice
for this file. This patch fixes that warning.
If there's a specific reason that this change is considered undesirable,
please do let me know why.

Hi Mauro.
Laurent and I discussed this driver a little on irc.
Some highlights:
This parts could use register names:

In nbu2ss_eq_queue() memory is allocated with dma_alloc_coherent(),
though, strangely, NULL is passed as the struct device* argument. Pass
the UDC's device instead. Fix up the corresponding call to
dma_free_coherent() in the same way.

The protection of the management frames is mainly done by mac80211.
However, frames for the management of the BlockAck sessions are directly
sent by the device. These frames have to be protected if MFP is in use.
So the driver has to pass the MFP configuration to the device.

Until now, hif_map_link() get as argument the raw value for

Now hif_map_link() takes explicit value for every flags of the
