Yes, thank you very much. 

I took a look at the relevant code and it should be upgraded to handle this
error gracefully, rather than the NULL-dereference it does now. I will handle
this follow-up change.

Did you test with anything later than BUS_PASS_INTERRUPT? It seems like the
only requirement is for the bcm_dma driver to attach before sdhci_bcm, so
BUS_PASS_SUPPORTDEV would be slightly more appropriate, if it works.
