NOTE: The patch will not be queued to stable trees until it is upstream.

How should we proceed with this patch?

The patch only makes sense in kernels that have ACPI support enabled for serdev devices, i.e., v4.15+. In the applicable kernels, it has a dependency on 33364d63c75d ("serdev: Add ACPI devices by ResourceSource field") as detected by the bot.

The patch does not need to be backported any further back.

Likely due to the holidays, Greg's not yet picked up the patch for upstream. I'll nudge him for feedback.

Thanks, Punit
