Subject[PATCH] scsi: qla2xxx: remove some redundant pointer assignments
Date
From: Colin Ian King <colin.king@canonical.com>

There are several local or function parameter pointers that are
being assigned NULL after a kfree where and these have no effect
and hence can be removed.

Fixes various cppcheck warnings:

"Assignment of function parameter has no effect outside the
function. Did you forget dereferencing it"
