Felipe Balbi ad1adb89a0 usb: musb: gadget: do not poke with gadget's list_head
struct usb_request's list_head is supposed to be
used only by gadget drivers, but musb is abusing
that. Give struct musb_request its own list_head
and prevent musb from poking into other driver's
business.

Mian Yousaf Kaukab c65bfa62b7 usb: musb: maintain three states for buffer mappings instead of two
If dma buffers are mapped by a higher layer, with a boolean musb_request.mapped
it is still possible to call dma_sync_single_for_device() from
musb_g_giveback(), even if txstate()/rxstate() has called unmap_dma_buffer()
before falling back to pio mode.

Moreover, check for musb_ep->dma is moved within map_dma_buffer() so where
applicable checks for it are removed. And where possible, checks for
is_dma_capable() are merged with buffer map state check.

Sergei Shtylyov a666e3e609 usb: musb: gadget: restart request on clearing endpoint halt
Commit 46034dca51 (USB: musb_gadget_ep0: stop
abusing musb_gadget_set_halt()) forgot to restart a queued request after
clearing the endpoint halt feature. This results in a couple of USB resets
while enumerating the file-backed storage gadget due to CSW packet not being
sent for the MODE SENSE(10) command.

Sergei Shtylyov 46034dca51 USB: musb_gadget_ep0: stop abusing musb_gadget_set_halt()
Stop playing with musb->lock and abusing musb_gadget_set_halt() in
the code clearing the endpoint halt feature -- instead, manipulate
the registers directly.

While at it, get rid uf unneeded line breaks and over-indentation in
the code setting the endpoint halt feature.
