Fix the drivers and add some docs according to the outcome of this discussion [1] we had recently. The motivation from the patch description: Bail out everytime when mmc_regulator_get_supply() returns an errno, not only when probing gets deferred. This is currently a no-op, because this function only returns -EPROBE_DEFER or 0 right now. But if it will throw another error somewhen, it will be for a reason. (This still doesn't change that getting regulators is optional, so 0 can still mean no regulators found). So, let us a) be future proof and b) have driver code which is easier to understand. The patches have been created with coccinelle. A branch can be found here: git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux.git renesas/mmc-get-supply-docs Looking forward to comments!
