It will break builds on A family whose rpm clocks are not based on SMD. IMO, this should be either renamed to clk-rpm-smd.* or only built with SOC's which support rpm-clks based on SMD. > clk-qcom-y += reset.o > -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
