Yes, but this pattern makes extra footprint of the kernel and basically dead code when I would like, for example, to have SPI bus enabled, I2C module available, but SPI module not compiled. Other one is when I want to have one compiled in, one as a module by whatever reason. At the end I have no strong opinion, though rationale for the opposite is above. -- With Best Regards, Andy Shevchenko -- To unsubscribe from this list: send the line "unsubscribe linux-iio" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
