I'm attaching the build log, which shows that the error is actually a missing function: net_random(). This function has been removed from the kernel in 3.14 with commit

    net: replace macros net_random and net_srandom with direct calls to prandom

Which means this is not really a regression, but an expected failure. Apparently, this DKMS packages was being built using the 3.13 kernel, even with the HWE kernels (lts-vivid and lts-utopic)
