Anyway, I think the change is good. On systems with multiple MMC devices the boot/probe can spend 100-200 ms alone just doing busylooping delays. I think e.g. in mmc_rescan() the code uses frequently mmc_delay(10).
I'm worrying about this: mmc_delay(DIV_ROUND_UP(card->ext_csd.sa_timeout, 10000)) since I have no ideas about typical values for this timeout. If it may be too small (<=10 us), using usleep_range() makes no sense.
