spi: rspi: Make qspi_set_send_trigger() return "unsigned int"
qspi_set_send_trigger() returns an unsigned value, so make it return "unsigned int". Update the loop variables qspi_trigger_transfer_out_int() to match the above. Signed-off-by: Geert Uytterhoeven <geert+renesas@glider.be> Signed-off-by: Mark Brown <broonie@kernel.org>
