Yes, SKL needs its own fix (version 1.27). Currently waiting for it to be
pulled to linux-firmware.git (after which the corresponding kernel patch needs
to be merged).

The pull request for the firmware is at:
https://lists.freedesktop.org/archives/intel-gfx/2017-November/146326.html

The firmware is in the following branch:
https://github.com/anushasr/linux-firmware/commits/SKL_DMC

The kernel patch:
