Most of the functions can be called in process context (can sleep), except
in some unlikely cases (printing an oops).
Of all the functions in there, make sure that fb_blank() cannot sleep.
and which functions may be called only between some fb_open

It's guaranteed that none of the functions will get called before
an fb_open() or after a successful fb_release().
