[PATCH 1/4] SCSI-QLA4...: Deletion of unnecessary checks before three function calls

[SF Markus Elfring]

From: Markus Elfring <elfr...@users.sourceforge.net>
Date: Fri, 6 Feb 2015 20:38:23 +0100

The following functions perform also input parameter validation.
* iscsi_boot_destroy_kset
* kfree
* vfree

Thus the test around their calls is not needed.

This issue was detected by using the Coccinelle software.
