Some drivers whose planes only support linear layout fb do not support format

These drivers should support modifiers, however the DRM core should handle this
rather than open-coding in every driver.
In this patch series, these drivers expose format modifiers based on the
following suggestion[1].
Thanks for the series, it looks like the right thing to do.
Can you please change the patch ordering though? At the moment there
will be a bisection break at patch #1, because the legacy drivers will
suddenly start gaining modifier support, before it is removed in patch
#2.
I think a better order would be:
1: add fb_modifiers_not_supported flag to core and drivers
2: add default modifiers (and set allow_fb_modifiers) if
fb_modifiers_not_supported flag is not set
3: remove allow_fb_modifiers flag
I agree to your proposal.
I will fix these patches.
