From: Colin Ian King <colin.king@xxxxxxxxxxxxx>
The variable n is being assigned a value that is never read inside
an if statement block, the assignment is redundant and can be removed.
With this removed, n is only being used for a constant loop bounds
check, so replace n with that value instead and remove n completely.
Addresses-Coverity: ("Unused value")

V2: remove the variable n completely, thanks to Dan Carpenter for
spotting this.
