Linus Torvalds 2ab002c755 Driver core and debugfs updates
Here is the big set of driver core and debugfs updates for 6.14-rc1.
 It's coming late in the merge cycle as there are a number of merge
 conflicts with your tree now, and I wanted to make sure they were
 working properly.  To resolve them, look in linux-next, and I will send
 the "fixup" patch as a response to the pull request.
 
 Included in here is a bunch of driver core, PCI, OF, and platform rust
 bindings (all acked by the different subsystem maintainers), hence the
 merge conflict with the rust tree, and some driver core api updates to
 mark things as const, which will also require some fixups due to new
 stuff coming in through other trees in this merge window.
 
 There are also a bunch of debugfs updates from Al, and there is at least
 one user that does have a regression with these, but Al is working on
 tracking down the fix for it.  In my use (and everyone else's linux-next
 use), it does not seem like a big issue at the moment.
 
 Here's a short list of the things in here:
   - driver core bindings for PCI, platform, OF, and some i/o functions.
     We are almost at the "write a real driver in rust" stage now,
     depending on what you want to do.
   - misc device rust bindings and a sample driver to show how to use
     them
   - debugfs cleanups in the fs as well as the users of the fs api for
     places where drivers got it wrong or were unnecessarily doing things
     in complex ways.
   - driver core const work, making more of the api take const * for
     different parameters to make the rust bindings easier overall.
   - other small fixes and updates
 
 All of these have been in linux-next with all of the aforementioned
 merge conflicts, and the one debugfs issue, which looks to be resolved
 "soon".
