Marek Behún 9fd8d4b53e bus: moxtet: fix potential stack buffer overflow
commit 3bf3c97446 upstream.

The input_read function declares the size of the hex array relative to
sizeof(buf), but buf is a pointer argument of the function. The hex
array is meant to contain hexadecimal representation of the bin array.
