Maybe also make it more explicit in the commit message that the delayed
work is replacing a timer that was used before for the cursor ?

A delayed_work uses a timer underneath but I wonder if the comment also

work that gets re-scheduled each time on fb_flashcursor().
The patch looks good to me and makes the logic much simpler than before.
