After 2 days of testing, this patch seems to fix the issue for me. No more spam of change event messages in udev, and udev cpu usage is back to normal.
Note, it's unclear to me how the patch would effect folks using, say, HDMI outputs with this chip. Someone who has such hardware needs should test.
