If you are using the Linux kernel from Ubuntu 14.04, such as 3.13.0-{39,40,43}-generic, those DKMS packages should not affect your system.
You can remove them by `sudo apt-get purge oem-audio-hda-daily-lts-quantal oem-wireless-bluetooth-intel-7260` if you think they are redundant.
`uname -r` can check the kernel version.
BTW, `ubuntu-drivers devices` may also provide the helpful information.
