spi: spi-xilinx: cleanup a check in xilinx_spi_txrx_bufs() ...
commit e33d085d11e54bc9fb07b2555cd104d8e7b3089b upstream.
'!' 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.
