Subject: [PATCH] drivers/misc: ti-st: remove redundant assignment to variable i

From: Colin Ian King <colin.king@...onical.com>

The variable i is being initialized with a value that is never
read and it is being updated later with a new value in a for-loop.
The initialization is redundant and can be removed.

Addresses-Coverity: ("Unused value")
