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

DESCRIPTION¶

This routine does essentially the same thing as usb_autopm_put_interface: it decrements intf´s usage counter and queues a delayed autosuspend request if the counter is <= 0. The difference is that it does not acquire the device´s pm_mutex; callers must 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.
