Subject[PATCH][V2] drivers/tty: remove redundant assignment to variable i and rename it to ret
Date
From: Colin Ian King <colin.king@canonical.com>

The variable i is being assigned a value that is never read
and it is being updated later with a new value. The assignment
is redundant and can be removed. Also rename i to ret as this new
name makes makes more sense.

Addresses-Coverity: ("Unused value")
