.TH "USB_DRIVER_RELEASE_INTERFACE" "9" "13 April 2004" "" ""

.SH NAME
usb_driver_release_interface \- unbind a driver from an interface
.SH SYNOPSIS
.sp
\fB
.sp
void usb_driver_release_interface  (struct usb_driver * \fIdriver\fB, struct usb_interface * \fIiface\fB);
\fR
.SH "ARGUMENTS"
.TP
\fB\fIdriver\fB\fR
the driver to be unbound
.TP
\fB\fIiface\fB\fR
the interface from which it will be unbound
.SH "DESCRIPTION"
.PP
In addition to unbinding the driver, this re-initializes the interface
by selecting altsetting 0, the default alternate setting.
.PP
This can be used by drivers to release an interface without waiting
for their \fBdisconnect\fR methods to be called.
.PP
When the USB subsystem \fBdisconnect\fRs a driver from some interface,
it automatically invokes this method for that interface.  That
means that even drivers that used \fBusb_driver_claim_interface\fR
usually won't need to call this.
.PP
This call is synchronous, and may not be used in an interrupt context.
Callers must own the driver model's usb bus writelock.  So driver
\fBdisconnect\fR entries don't need extra locking, but other call contexts
may need to explicitly claim that lock.
