Right, this post was just a single patch in isolation, whereas it was reposted over at: https://lore.kernel.org/r/cdcc6a1c95a84e774790389dc8b3b7feeee490dc.1593344119.git.saiprakash.ranjan@codeaurora.org so I'll ignore this one. Sorry, I'm just really struggling to keep track of what is targetting 5.9, and I don't have tonnes of time to sift through the backlog of duplicate postings :( Will _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
