If the struct mmc_pwrseq_match .alloc function used to allocate a struct mmc_pwrseq fails, the error is propagated to mmc_of_parse(). But instead of returning the error code in pwrseq, host->pwrseq is returned which will always be 0. So mmc_of_parse() succeeds even if the pwrseq .alloc function failed and host->pwrseq is NULL. This makes the SDIO device to not be powered if the power sequencing .alloc functions wants to be deferred due a missing resource because the mmc controller driver probe did wrongly succeed.
