[PATCH] drm/i915/dsi: Make Lenovo Yoga Tab 3 X90F DMI match less strict

[Hans de Goede]

There are 2G and 4G RAM versions of the Lenovo Yoga Tab 3 X90F and it
turns out that the 2G version has a DMI product name of
"CHERRYVIEW D1 PLATFORM" where as the 4G version has
"CHERRYVIEW C0 PLATFORM". The sys-vendor + product-version check are
unique enough that the product-name check is not necessary.

Drop the product-name check so that the existing DMI match for the 4G
RAM version also matches the 2G RAM version.

Thank you.

I was going to push this directly to drm-intel-fixes, but reading:

https://drm.pages.freedesktop.org/maintainer-tools/repositories/drm-intel.html#repository-and-branches

It seems that I should push this to drm-intel-next and then cherry-pick
it into drm-intel-fixes ?

Regards,

Hans

Just push to drm-intel-next and let the fixes tag take care of its magic:

Fixes: f6f4a0862bde ("drm/i915/vlv_dsi: Add DMI quirk for backlight control issues on Lenovo Yoga Tab 3 (v2)")

The cherry-pick to -fixes branches is handled weekly by whoever maintainer
is tacking care of that round. Usually the 'Fixes' tag will be enough to ensure
it gets propagated. But on the lack of the fixes tag of if you noticed something was missed,
then just ping us.

Thanks,
Rodrigo.

Thanks. I've pushed this to drm-intel-next now with the fixes tag added.
