Set? Why bother? If anything reset_resume() is hopeless, so why
delay the resume by trying?
hi Oliver:
Maybe my change log confuse you.I mean the persist_enabled should be
changed when USB_QUIRK_RESET_MORPHS is changed, right?
When USB_QUIRK_RESET_MORPHS is set, persist_enabled should be set to 0
to prevent reset-resume() when the device resumes.
Current only in the usb_detect_quirks(), persist_enabled will
be set to 0 depending on whether the dev's flag USB_QUIRK_RESET_MORPHS
is set or not. And usb_detect_quirks() is only called in the
hub_port_connect_change() when a new device is found.
So after a device being enumerated, Changing attribute avod_reset_quirk
will not set persist_enabled to 0 to prevent reset-resume.
If something wrong, please help me to correct. Thanks.
Regards
Oliver
