Actually, this probably isn't necessary -- mmc_app_cmd() is the only call
involved in the setup path, via mmc_sd_init_card() -> mmc_app_send_scr().

So, a better question: was mmc_app_send_scr() succeeding on your previous
kernels?  There hasn't been much change in this area lately.

Thanks,

- Chris.
