NAME

6       usb_autopm_put_interface_async - decrement a USB interface's PM-usage
7       counter
8

SYNOPSIS

10       void usb_autopm_put_interface_async(struct usb_interface * intf);
11

ARGUMENTS

13       intf
14           the usb_interface whose counter should be decremented
15

DESCRIPTION

17       This routine does much the same thing as usb_autopm_put_interface: It
18       decrements intf's usage counter and schedules a delayed autosuspend
19       request if the counter is <= 0. The difference is that it does not
20       perform any synchronization; callers should hold a private lock and
21       handle all synchronization issues themselves.
22
23       Typically a driver would call this routine during an URB's completion
24       handler, if no more URBs were pending.
25
26       This routine can run in atomic context.
