Just to note, it might be in linux-next, but more importantly it is also
in v6.5-rc1, so there is no issue with dependencies.

I noticed you sent a mail pinging the v4 of this series yesterday as it
had not been picked up. Who do you actually expect to apply these
patches? There does not appear to be a maintainer listed for the
drivers/soc/loongson directory, just one for your GUTS driver.

As a result, patches like
<https://lore.kernel.org/all/a69170cb55cfc73e378b40ccf1d9c16f@208suo.com/>
have gone ignored. Granted, that patch is probably crap that does not
apply, due to 208suo.com people sending corrupted patches, but you the
point.

More interestingly there is also
<https://lore.kernel.org/all/40b324af-3483-4b3d-b65a-a97944aa4a70@app.fastmail.com/>
which seems to have also gone missing (I don't see it in linux-next),
despite some discussion about how the patch should be merged.

Looks to me like drivers/soc/loongson/ needs someone to take
responsibility for picking up patches for the directory & sending them
to the soc maintainers (with a new MAINTAINERS entry reflecting that) so
that patches don't fall through the cracks.

Thanks,
Conor.
