USB_AUTOPM_GET_INTER(9) USB Core APIs USB_AUTOPM_GET_INTER(9)NAMEusb_autopm_get_interface_async - increment a USB interface's PM-usage
counter
SYNOPSIS
int usb_autopm_get_interface_async(struct usb_interface * intf);
ARGUMENTS
intf
the usb_interface whose counter should be incremented
DESCRIPTION
This routine does much the same thing as usb_autopm_get_interface: It
increments intf's usage counter and queues an autoresume request if the
device is suspended. The differences are that it does not perform any
synchronization (callers should hold a private lock and handle all
synchronization issues themselves), and it does not autoresume the
device directly (it only queues a request). After a successful call,
the device may not yet be resumed.
This routine can run in atomic context.
