1. Is this actually correct? Since mmc1 was disabled, sdhci_2 had mmc1
index but now will have mmc2.
2. I tested Odroid U3 and the ID changed. emmc went from 1 to 0. Any
idea why? Both patches should be transparent.
3. Patchset does not look bisectable, so both patches should be squashed.
4. Your patch has several whitespace issues:
patch:264: trailing whitespace.
patch:279: trailing whitespace.
patch:461: trailing whitespace.
Best regards,
Krzysztof
