Name
usb_interface_claimed —
returns true iff an interface is claimed
Synopsis
int usb_interface_claimed ( | struct usb_interface * iface); |
Arguments
iface
the interface being checked
Return
true (nonzero) iff the interface is claimed, else false
(zero).
Note
Callers must own the driver model's usb bus readlock. So driver
probe entries don't need extra locking, but other call contexts
may need to explicitly claim that lock.
