WARNING: with this patch usb-otg-fsm module can be loaded
but then the kernel will hang. Tested with a udoo quad board.

I don't know why I can't apply your patch, does it make on
an very old version?
I apply it manually, thanks.
Hi Peter,
Thanks for applying my first patch to linux! :)
As I said on the commit message, although I can load ci_hdrc_imx just
fine, it doesn't work because as soon as it's loaded, the kernel hangs
without any error or message at all.
This happens on my udoo quad board (imx6q). Of course, if I blacklist
the ci_hdrc_imx module (appending modprobe.blacklist=ci_hdrc_imx as boot
parm) I can login the system, but no usb devices are found. Alexander
Graf from Suse said that this sounds like a clock problem.
Let me know how can I help you to resolve the problem.
Cheers,
