Subject: [PATCH] ftrace: remove redundant assignment to pointer 'name'

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

The pointer 'name' is being initialized with a value that is never read
and it is being updated later with a new value. The initialization
is redundant and can be removed. Replace it with the later assignment.

Addresses-Coverity: ("Unused value")
