Merge tag 'driver-core-6.0-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core
Pull driver core fixes from Greg KH:
"Here are some small driver core and debugfs fixes for 6.0-rc5.
Included in here are:
- multiple attempts to get the arch_topology code to work properly on
non-cluster SMT systems. First attempt caused build breakages in
linux-next and 0-day, second try worked.
- debugfs fixes for a long-suffering memory leak. The pattern of
debugfs_remove(debugfs_lookup(...)) turns out to leak dentries, so
add debugfs_lookup_and_remove() to fix this problem. Also fix up
the scheduler debug code that highlighted this problem. Fixes for
other subsystems will be trickling in over the next few months for
this same issue once the debugfs function is merged.
All of these have been in linux-next since Wednesday with no reported
problems"
