Subject: [PATCH] misc: pti: remove redundant assignments to retval

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

The variable retval is assigned with a value that is never read and
it is re-assigned a new value later on.  The assignment is redundant
and can be removed.  Clean up multiple occurrances of this pattern.

Addresses-Coverity: ("Unused value")
