Subject: [GIT PULL] Driver core changes for 6.17-rc1
Hi Linus,
Please pull these driver-core changes.
There is one trivial conflict with your tree in rust/helpers/helpers.c.
There are also some non-trivial conflicts with Miguel's Rust tree. Additional to
the resolutions in linux-next, which should be correct, I also did a test merge
with Miguel's tree:
https://git.kernel.org/pub/scm/linux/kernel/git/driver-core/driver-core.git driver-core-6.17-test-merge
All commits have been in linux-next for over a week with no reported issues.
Independently, preparing this PR I noticed one minor issue with one of the
debugfs changes. I already sent a fix [1] for this, which should reach you
through a normal -fixes PR (unless you decide to pick it right away).
