[Intel-gfx] Question about latest skl_dmc_ver1_27.bin and kernel version.

I am trying to setup Intel's new open-source iHD driver on a Yocto
The documentation says that skl_dmc_ver1_27.bin is required. Their
documentation updates a symlink (skl_dmc_ver1.bin), as if the kernel loads
it, but starting at kernel 4.8, it stopped loading the symlink and instead
loads a specific version of the dmc (see here:
Is the Intel documentation accurate? It is confusing because the guide
refers to 4.14.16 specifically, which doesn't use the symlink file
Any ways, I tried replacing skl_dmc_ver1_26.bin with skl_dmc_ver1_27.bin to
have the same effect, but I got a segfault on boot.
Should I even bother updating the DMC? Should the iHD driver work on most
kernels, even with 1_26 version of DMC?
By the way, this is the kernel I am using (with Yocto).
Any help would be greatly appreciated. There is no documentation on this
