The patch titled
Avoid race when deregistering the IR control for dvb-usb
has been removed from the -mm tree. Its filename was
avoid-race-when-deregistering-the-ir-control-for-dvb-usb.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
Subject: Avoid race when deregistering the IR control for dvb-usb
From: Chris Rankin <rankincj@xxxxxxxxx>
The work item function is dvb_usb_read_remote_control():
INIT_WORK(&d->rc_query_work, dvb_usb_read_remote_control, d);
and the last piece of work it does is:
schedule_delayed_work(&d->rc_query_work,msecs_to_jiffies(d->props.rc_interval));
Hence you need to call "cancel_rearming_delayed_work()" and not
"cancel_delayed_work()", correct? I certainly haven't seen this oops
reoccur since I applied this patch.
