Random drivers should not override a user configuration of core knobs (e.g., CONFIG_DMA_CMA=n). Use "imply" instead, to still respect dependencies and manual overrides. "This is similar to "select" as it enforces a lower limit on another symbol except that the "implied" symbol's value may still be set to n from a direct dependency or with a visible prompt." Implying DRM_CMA should be sufficient, as that depends on CMA. Note: If this is a real dependency, we should use "depends on DMA_CMA" instead - but I assume the driver can work without CMA just fine -- esp. when we wouldn't have HAVE_DMA_CONTIGUOUS right now.
