This is still a driver bug that needs to be fixed. I just sent a fix a
here:

	https://lore.kernel.org/lkml/20250624082022.15469-1-johan+linaro@kernel.org/

Also note that there is no board file for the CRD in linux-firmware
(yet, see [1]), but apparently that is not enough to cause probe to fail
(unlike completely missing firmware).
