If my understanding is correct, that one is needed, as you will need to do a reset after failing to probe at one freq and then trying another one. Or do you mean a patch to add sdio_reset() into the runtime PM powerup path? That would be harmless, would increase consistency between the codepaths, and would solve this issue, so naturally has my vote :) Add sdio_reset() !! To the code path Thanks Daniel -- To unsubscribe from this list: send the line "unsubscribe linux-mmc" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
