What happened to this patch? I have a 10 second timeout on console
probe on my SiFive Unmatched, and I don't see this flag being set for
the serial driver. In fact, I don't see it anywhere in-tree. I can't
seem to locate another patchset from Saravana around this though, so
I'm not sure where to look for a missing piece for the sifive serial

This is the second boot time regression (this one not fatal, unlike
the Layerscape PCIe one) from the fw_devlink patchset.

Greg, can you revert the whole set for 6.0, please? It's obviously
nowhere near tested enough to go in and I expect we'll see a bunch of
-stable fixups due to this if we let it remain in.

This seems to be one of the worst releases I've encountered in recent
years on my hardware here due to this patchset. :-(
