Subjectv3.11-rc1 USB regressions
Hi,

I think USB tree introduced regressions in v3.11-rc1, at least for some
OMAP devices using legacy boot. I have only bisected these; I have no
idea what the real fixes are but the following reverts make Nokia OMAP2+
boards again usable for kernel development work (they need working USB
connection for interacting with the device):

1) USB peripheral mode (g_ether) is broken on Nokia N900, N950 and N9
(USB_MUSB_OMAP2PLUS). To make it it work, I need to revert three
commits:

09fc7d22b024692b2fe8a943b246de1af307132b
usb: musb: fix incorrect usage of resource pointer
(Reverting this fixes the g_ether probe failure "couldn't find
an available UDC")

fe4cb0912f8e737f8e4b8b38b9e692f8062f5423
usb: musb: gadget: remove hcd initialization
(Reverting this fixes error "cdc_ether: probe of 4-1:1.0 failed
with error -110" seen on the host side.)

8b125df5b24cfb0ec7fa1971e343cc0badc1827d
usb: musb: eliminate musb_to_hcd
(Reverting this fixes compilation error cause by the previous
revert.)

2) USB peripheral mode (g_ether) is broken also on Nokia N800 and N810
(USB_MUSB_TUSB6010). In addition to the above, I need to also revert
the following:

b7e2e75a8c6062afe1dd88b0b299938e5d36dff8
usb: gadget: drop unused USB_GADGET_MUSB_HDRC

(This commit is clearly incorrect - code checking for this still
remain in the tree (see e.g. N8x0 board file), so it's not "unused".)

A.
