           Summary: graphics/drm-fbsd13-kmod fails to build after LinuxKPI

Since the commits on 17-Jul to update the linuxkpi to support iwlwifi and other
issues, drm-fbsd13-kmod will no longer build. make buildworld also fails while
building the kernel module, as well with the same issues with strings.

From UPDATING:
20210718:
        Bump __FreeBSD_version to 1300512 after merging LinuxKPI, OFED,
        net80211, and driver changes in order to support building
        Intel wireless iwlwifi drivers.  This is especially needed for
        drm-kmod which needs updates after this.

It reads like this was committed with knowledge that it would likely break
buildkernel on STABLE. Huh! I hope I'm misreading this as STABLE should not get
updates which are known will break the kernel for may users.
