Yes, I will push these patches upstream later today.

Is there really a regression? If the DMI matching doesn't work, we fall
back to the old detection method, so I can't see how there would be a
regression. Care to explain?
(Which doesn't mean we can't push the patches to stable, as stable
isn't limited to regressions. Just trying to understand.)
Speaking of DMI matching... If DMI is disabled, we do:
static inline int abituguru3_dmi_detect(void)
And this error value causes abituguru3_init() to bail out. Unless I'm
missing something, the abituguru3 driver is simply useless without DMI
support at the moment. We should either make that official and make the
driver depend on DMI at Kconfig level, or change
abituguru3_dmi_detect() to return 1, so that we fallback to the old
detection method. Opinions?
