spi: Return error from of_spi_register_master on bad "cs-gpios" property This makes sure that an error is returned on an incorrectly formed "cs-gpios" property, but reports success when the "cs-gpios" property is well formed or missing. When holes in the cs-gpios property phandle list is used to indicate that some other form of chipselect is to be used it is important that failure to read a broken "cs-gpios" property does not silently fail leading to the spi controller to use an unintended chipselect.
