pxa27x_udc: Oops on probe with usb cable connected.

[Antonio Ospite]

Hi,

this is a quite old issue but I'd like to bring it back on.
I get this Oops when pxa27x_udc is probed with the usb cable plugged,
this happens on a Motorola A780 phone using the openezx kernel[1] and
the gen-blob[2] second stage bootloader which disables the UDC before
booting the kernel from flash.

See the trace here:
http://people.openezx.org/ao2/tmp/pxa27x-udc_BUG/log_CRASH.txt

Here is the log of a working case (cable not plugged):
http://people.openezx.org/ao2/tmp/pxa27x-udc_BUG/log_OK.txt

Note that using the original blob bootloader from Motorola there is no
Oops but the UDC does not work at all, but maybe this is another
issue, I mean: should pxa27x_udc probe consider the case when UDC is
already active?

Here a log for this last case:
http://people.openezx.org/ao2/tmp/pxa27x-udc_BUG/log_NOCRASH_NOT_WORKING.txt

Tell me how can i help debugging this, I've put the binary and the
disassembled code in http://people.openezx.org/ao2/tmp/pxa27x-udc_BUG/
plus some notes about old discussions on the same matter.

Thanks,
   Antonio
