I have some minor comments on each patch, but also I don't agree with the patch splitting: what's the point in splitting and sending one patch per file? It doesn't make it any easier to review, so why don't you just send one patch: "Introduce smi2021 driver"? The rule is one patch per change, and I believe this whole patchset is just one change: adding a new driver. -- Ezequiel García, Free Electrons Embedded Linux, Kernel and Android Engineering http://free-electrons.com -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
