Dear Peter Chen, > Since we introduce -EPROBE_DEFER for udc driver, it will be > probed at late_initcall if it is defered.

That's the problem we met at below link: > > http://marc.info/?l=linux-usb&m=137706435611447&w=2 > > We have no driver's probe at gadget driver, so we can't return > -EPROBE_DEFER. And it is also not suitable to defer udc_bind_to_driver > if the udc is not found temporarily, since it is hard to decide the > return value for usb_gadget_probe_driver. > > Due to above reasons, mark gadget's init as late_initcall may be a > moderate solution. > > Signed-off-by: Peter Chen <peter.chen@xxxxxxxxxxxxx> Seems this tries to paper over an issue with module dependencies , no?
