Per sandbox_cs_info(), sandbox spi controller only supports chip select 0. Current test case tries to locate devices on chip select 1, and any call to spi_get_bus_and_cs() or spi_cs_info() with cs number 1 should not return 0. This updates the test case to handle it correctly. Signed-off-by: Bin Meng <bmeng.cn@gmail.com> Reviewed-by: Jagan Teki <jagan@amarulasolutions.com>
