USB_AUTOPM_PUT_INTER(9) USB Core APIs USB_AUTOPM_PUT_INTER(9)
NAME
usb_autopm_put_interface_async - decrement a USB interface's PM-usage
counter
SYNOPSIS
void usb_autopm_put_interface_async(struct usb_interface * intf);
ARGUMENTS
intf
the usb_interface whose counter should be decremented
DESCRIPTION
This routine does much the same thing as usb_autopm_put_interface: It
decrements intf's usage counter and schedules a delayed autosuspend
request if the counter is <= 0. The difference is that it does not
perform any synchronization; callers should hold a private lock and
handle all synchronization issues themselves.
Typically a driver would call this routine during an URB's completion
handler, if no more URBs were pending.
This routine can run in atomic context.
