The original is fine/better.

I don't like how the < 0 is on the next line.  It would be better to
introduce an "int ret;"
			ret = kp_spi_wait_for_reg_bit(cs, KP_SPI_REG_STATUS,
						      KP_SPI_REG_STATUS_TXS);
			if (ret < 0)
				goto out;

Move the whole conition down:

		if (transfer->speed_hz &&
		    transfer->speed_hz < (KP_SPI_CLK >> 15)) {
