spi: omap2_mcspi PIO RX fix
Before transmission of the last word in PIO RX_ONLY mode rx+tx mode
is enabled:
/* prevent last RX_ONLY read from triggering
* more word i/o: switch to rx+tx
*/
if (c == 0 && tx == NULL)
mcspi_write_cs_reg(spi,
OMAP2_MCSPI_CHCONF0, l);
But because c is decremented after the test, c will never be zero and
rx+tx will not be enabled. This breaks RX_ONLY mode PIO transfers.
Fix it by decrementing c in the beginning of the various I/O loops.
