3.16.62-rc1 review patch. If anyone has any objections, please let me know.
------------------
From: Mikulas Patocka <mpatocka@xxxxxxxxxx>
commit 09a00abe3a9941c2715ca83eb88172cd2f54d8fd upstream.
We must use kzalloc when allocating the fb_deferred_io structure.
Otherwise, the field first_io is undefined and it causes a crash.
