USB_AUTOPM_GET_INTER(9)                   USB Core APIs                   USB_AUTOPM_GET_INTER(9)



NAME
       usb_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.

RETURN
       0 on success. A negative error code otherwise.
