Add __user annotation to buf, as it is passed as a user pointer in
pin_user_pages_fast(). Use an empty initializer for the sentinel
board-table entry to avoid initializing a function pointer with an
integer literal.

FTR: Using 0 in an initializer is covered by the C standard. Anyhow, I
agree that { } is nicer.

Having said that, I think the right thing to do here is to drop the
sentinel entry, because board_driver[] is only used in for loops that
iterate between 0 (inclusive) and ARRAY_SIZE(board_driver) (exclusive).

Also I would split this patch in two.
