[PATCH 08/27] usb: chipidea: move debug files creation/removal to the core

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Create and remove debugfs entries in hdrc probe/remove instead of
start/stop of the device controller. Gadget specific will not export
anything while the controller is in host mode.
