If only linear modifier is advertised, since there are many drivers that
only linear supported, the DRM core should handle this rather than
open-coding in every driver. However, there are legacy drivers such as
radeon that do not support modifiers but infer the actual layout of the
underlying

dma-buf-map is being phased out in favor of the equivalent and renamed
interface: iosys-map. Use the new header in documentation.

This seems short-sighted. If the patch is valid I see
This reverts commit 2343bcdb4747d4f418a4daf2e898b94f86c24a59.
Unfortunately, as Greg pointed out I totally missed the fact that this
patch came from a umn.edu patch. umn.edu is still banned from contributing
to the Linux kernel, so let's revert this for the time being. I'll
re-evaluate this fix
Sigh-thank you for catching this - I had totally forgot about the umn.edu ban.
I pushed this already but I will go ahead and send a revert for this patch.
Will cc you on it as well.
