Subject: [PATCH 3.16 064/129] iscsi_ibft: Fix missing break in switch
 statement

3.16.70-rc1 review patch.  If anyone has any objections, please let me know.

------------------

From: "Gustavo A. R. Silva" <gustavo@...eddedor.com>

commit df997abeebadaa4824271009e2d2b526a70a11cb upstream.

Add missing break statement in order to prevent the code from falling
through to case ISCSI_BOOT_TGT_NAME, which is unnecessary.

This bug was found thanks to the ongoing efforts to enable
-Wimplicit-fallthrough.
