Subject: Intel Wireless 7260 failed to work

Hello,

Looks like latest Linux master (4.10-rc1, 7ce7d89f) cannot work well
with my wireless card, which is:

  Intel Corporation Wireless 7260 (rev bb)

Boot message shows that no suitable firmware found:

    # journalctl -kp3
    Dec 27 16:38:00 kernel: Error parsing PCC subspaces from PCCT
    Dec 27 16:38:00 kernel: mmc0: Unknown controller version (3). You may experience problems.

    Dec 27 16:38:04 kernel: iwlwifi 0000:03:00.0: no suitable firmware found!

Linux stable/master (Linux 4.8-rc8, 08895a8b6b) works for me. And no
further tests have been done yet.

Is this a known issue? Please let me know if anyone wants more info or
logs, since this error triggers easily (everytime I boot).

Thanks,
