The only reason you can remove those headers is because you are obtaining things indirectly via qca_7k.h And if that is indeed the case, you are also getting qca_spi.h which in turn includes linux/spi/spi.h So you could have removed that as well. But seriously, it is so much harder to understand a driver and what interfaces it needs via header files when you hide _all_ of it behind these local private header files which just include _everything_ and then _every_ foo.c file in your driver gets _all_ of those kernel headers whether they need it or not. So if just one foo.c file needs 20 extra kernel headers than the rest of the files in the driver, every foo.c file eats that cost of including them. I really don't like when drivers move in this direction for that reason. And at best, as described at the beginning of my response, this change is incomplete. -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
