Please CC Cong Yang (CCed here) on your next version since he's also
touching this file and your changes will conflict with his.

nit: since the "multi" functions print errors for you, you can get rid
of the (now duplicate) error print in the caller. I guess if you
really wanted to you could actually just inline
boe_panel_enter_sleep_mode() into its one caller and that would make
it easy to use the "_multi" version of msleep() there...
In any case, I think this looks nice:
