I assume you would prefer me to post the other 2 patches once this lands in your -next. Worst case I would like to get the generic patch in along with ACPICA changes, I can then route the arm64 specific next cycle if it gets too late for v5.20 -- Regards, Sudeep _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
