Hi all,

After merging the hwmon-staging tree, today's linux-next build
(x86 allmodconfig) failed like this:

Caused by an interaction with Linus' tree. I have used the hwmon tree
from 20241128 instead.

Yes, that is due to the MODULE_IMPORT_NS API change in the upstream kernel
that was pushed right after -rc1. I'll push a new version after I build tested it.
