Linus Torvalds 500a434fc5 Driver core changes for 5.19-rc1
Here is the set of driver core changes for 5.19-rc1.
 
 Note, I'm not really happy with this pull request as-is, see below for
 details, but overall this is all good for everything but a small set of
 systems, which we have a fix for already.
 
 Lots of tiny driver core changes and cleanups happened this cycle,
 but the two major things were:
 
 	- firmware_loader reorganization and additions including the
 	  ability to have XZ compressed firmware images and the ability
 	  for userspace to initiate the firmware load when it needs to,
 	  instead of being always initiated by the kernel. FPGA devices
 	  specifically want this ability to have their firmware changed
 	  over the lifetime of the system boot, and this allows them to
 	  work without having to come up with yet-another-custom-uapi
 	  interface for loading firmware for them.
 	- physical location support added to sysfs so that devices that
 	  know this information, can tell userspace where they are
 	  located in a common way.  Some ACPI devices already support
 	  this today, and more bus types should support this in the
 	  future.
 
 Smaller changes included:
 	- driver_override api cleanups and fixes
 	- error path cleanups and fixes
 	- get_abi script fixes
 	- deferred probe timeout changes.
 
 It's that last change that I'm the most worried about.  It has been
 reported to cause boot problems for a number of systems, and I have a
 tested patch series that resolves this issue.  But I didn't get it
 merged into my tree before 5.18-final came out, so it has not gotten any
 linux-next testing.
 
 I'll send the fixup patches (there are 2) as a follow-on series to this
 pull request if you want to take them directly, _OR_ I can just revert
 the probe timeout changes and they can wait for the next -rc1 merge
 cycle.  Given that the fixes are tested, and pretty simple, I'm leaning
 toward that choice.  Sorry this all came at the end of the merge window,
 I should have resolved this all 2 weeks ago, that's my fault as it was
 in the middle of some travel for me.
 
 All have been tested in linux-next for weeks, with no reported issues
 other than the above-mentioned boot time outs.
