Merge tag 'iwlwifi-for-kalle-2016-01-26_2' of https://git.kernel.org/pub/scm/linux/kernel/git/iwlwifi/iwlwifi-fixes

* Fix support for 3168 device
        + NVM version
        + firmware file name
        + device IDs
* Fix a compilation warning in dvm calibration code
* Fix the TPC (reduced Tx Power) code. This fixes performance issues
* Device IDs for 8265
