mmc: usdhi6rol0: handle probe deferral for regulator
We ignore errors from mmc_regulator_get_supply() because the usage of the regulators is optional for the driver, but we still need to check for and handle EPROBE_DEFER, like it's done in for example dw_mmc. Otherwise we might end up not using the specified regulators just because of probe order. Signed-off-by: Rabin Vincent <rabin.vincent@axis.com> Signed-off-by: Ulf Hansson <ulf.hansson@linaro.org>
