You now have bumped the reference count on this structure. Where do you
decrement it when you are finished with it?
With context this time. Sorry about that.
That happens when I "unlink" the block device from the LED in
blkdev_disk_unlink_locked() at ledtrig-blkdev.c:410.
(And also in the error path of link_device_store() at
ledtrig-blkdev.c:372.)
