2011-06-03gpio/74x164: remove unnecessary defines and prototypeH Hartley Sweeten1-2/+0
Remove the #define GEN_74X164_GPIO_COUNT since it's only used in one place and it's meaning is obvious. Also remove the #define GEN_74X164_DRIVER_NAME and use spi->modalias to set the gpio chip's label and the string "74x164" for the driver name. Reorder the code slightly to remove the need to prototype gen_74x164_set_value. Signed-off-by: H Hartley Sweeten <hsweeten@visionengravers.com> Signed-off-by: Grant Likely <grant.likely@secretlab.ca>
