Frankly, this patch is a mess.  It seems to contain unrelated changes.

Please always review your own patches before you send them - this will
allow you to catch such errors before you post them publically.

The change to clcdfb_sleep() is wrong in any case - you will end up
calling schedule_timeout() from illegal contexts (eg, when the
framebuffer gets blanked/unblanked.)
