Hi Zhang, After merging the thermal tree, today's linux-next build (powerpc allyesconfig) produced this warning: warning: (HISI_THERMAL) selects STUB_CLK_HI6220 which has unmet direct dependencies (COMMON_CLK && COMMON_CLK_HI6220 && MAILBOX) Introduced by commit 5f63581ce68e ("thermal: hisilicon: Add dependency on the clock driver to allow frequency scaling") BTW: That commit message does not match the change (which adds a "select" not a "depends on". -- Cheers, Stephen Rothwell -- To unsubscribe from this list: send the line "unsubscribe linux-next" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
