[ 30/41] block, sx8: fix pointer math issue getting fw version

[Greg KH]

3.2-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Dan Carpenter <dan.carpenter@xxxxxxxxxx>

commit ea5f4db8ece896c2ab9eafa0924148a2596c52e4 upstream.

"mem" is type u8.  We need parenthesis here or it screws up the pointer
math probably leading to an oops.
