This is not the normal kernel style, which puts operators at the end
of the line.  And while a little more verbose I think a switch statement
would be a lot more readable here:

	switch (cmd->opcode) {
	case MMC_GO_IDLE_STATE:
	case MMC_SEND_OP_COND:
	case MMC_ALL_SEND_CID:
	case MMC_SET_RELATIVE_ADDR:
	case MMC_SET_DSR:
	case MMC_SLEEP_AWAKE:
	case MMC_SELECT_CARD:
	case MMC_SEND_CSD:
	case MMC_SEND_CID:
	case MMC_SEND_STATUS:
	case MMC_GO_INACTIVE_STATE:
	case MMC_APP_CMD:
		return false;
	default:
		return true;
	}
