Hello,
there must be a misunderstanding;
There is a functional change, because with the line/patch ".reset_resume =
usb_audio_resume," the mixer of the usb headset was not removed during
suspend/resume and so the master channel in KDE Mixer was not changed (Headset), which is
the correct beha
The idea of this message is: the non-ep0 should not use ctrl
transfer. But it does not cover the ep0in which uses ctrl
transfer too.
This commit deletes the warning message at interrupt handler,
and adds judgement at ep_enable, if non-ep0 requests ctrl transfer,
it will indicate an error.

This patchset adds USB OTG HNP and SRP support on chipidea usb driver,
existing OTG port role swtich function by ID pin status kept unchanged,
based on that, if select CONFIG_USB_OTG_FSM, OTG HNP and SRP will be
supported.

Would you have ci_vbus_handler to handle both OTG and non-OTG condition?
Besides, after doing that, you can have another patch only for init OTG
port number.
