6.6-stable review patch. If anyone has any objections, please let me know.

commit e2fe0c54fb7401e6ecd3c10348519ab9e23bd639 upstream.
On some chipsets, which block-linear modifiers are supported is format-specific. However, linear modifiers are always be supported. The prior modifier filtering logic was not accounting for the linear case.
