[Bug 1376800] [NEW] iscsitarget doesn't support kernel-ppa 3.14 or 3.16

[Walter Huf]

Public bug reported:

I'm using an updated kernel from http://kernel.ubuntu.com/~kernel-
ppa/mainline/ on Ubuntu 14.04. The DKMS (iscsitarget-dkms
1.4.20.3+svn499-0ubuntu2) fails to build for both 3.14 or 3.16, with the
following error:

Kernel preparation unnecessary for this kernel.  Skipping...
