spi: spi-xilinx: cleanup a check in xilinx_spi_txrx_bufs()
'!' has higher precedence than comparisons so the original condition is equivalent to "if (xspi->remaining_bytes == 0)". This makes the static checkers complain. xspi->remaining_bytes is signed and from looking at the code briefly, I think it might be able to go negative. I suspect that going negative may cause a bug, but I don't have the hardware and can't test. Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com> Signed-off-by: Mark Brown <broonie@linaro.org>
