I know that in wlcore\spi.c, I need to set a .power function in spi_ops (i.e. .power = wl12xx_spi_power). And I already have a wl12xx_platform_data with a .set_power function defined in my board platform file. But I don't know how to access my platform file's set_power function from the wl12xx_spi_power function in spi.c. In other words, I can' figure out how to do this from wlcore\spi.c: static int wl12xx_spi_power(struct device *child, bool enable) { set_power_function_defined_in_my_board_platform_file(enable); } -- To unsubscribe from this list: send the line "unsubscribe linux-wireless" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
