Greetings, 0day kernel testing robot got the below dmesg and the first bad commit is https://git.kernel.org/pub/scm/linux/kernel/git/jkirsher/next-queue.git dev-queue commit 1ca163afb6fd569b6efdc221954177cba5a02cbc Author: Greg Kroah-Hartman <gregkh(a)linuxfoundation.org&gt; AuthorDate: Sun Aug 27 17:03:31 2017 +0200 Commit: David S. Miller <davem(a)davemloft.net&gt; CommitDate: Mon Aug 28 16:42:56 2017 -0700 irda: move net/irda/ to drivers/staging/irda/net/ It's time to get rid of IRDA. It's long been broken, and no one seems to use it anymore. So move it to staging and after a while, we can delete it from there. To start, move the network irda core from net/irda to drivers/staging/irda/net/ Signed-off-by: Greg Kroah-Hartman <gregkh(a)linuxfoundation.org&gt; Signed-off-by: David S.
