The review to v4 showed about only the usage of cancel_work_*(),
and the suggestion sounds reasonable.  Those new cancel_work_*()
should be put before disabling i2c.

BTW, at the remove patch, maybe better to use disable_work*() variant
than cancel_work*().  The existing code is old and they were before
disable_*() was introduced (so they should be replaced, too).
