Dan Carpenter c6e1650cf5 speakup: Fix sizeof() vs ARRAY_SIZE() bug
commit 008ab3c53bc4f0b2f20013c8f6c204a3203d0b8b upstream.

The "buf" pointer is an array of u16 values.  This code should be
using ARRAY_SIZE() (which is 256) instead of sizeof() (which is 512),
otherwise it can the still got out of bounds.
