spi: imx: remove unnecessary check in spi_imx_can_dma
The spi_imx_can_dma function computes the watermark level so that the transfer will fit in exactly N bursts (without a remainder). The smallest watermark level possible being one FIFO entry per burst, we can't never have a case where the transfer size isn't divsiible by 1. Remove the extra check for the wml being different than 0. Signed-off-by: Maxime Chevallier <maxime.chevallier@bootlin.com> Signed-off-by: Mark Brown <broonie@kernel.org>
