Pull CXL (Compute Express Link) fixes from Dan Williams:
 "A collection of CXL fixes.

  The touch outside of drivers/cxl/ is for a helper that allocates
  physical address space. Device hotplug tests showed that the driver
  failed to utilize (skipped over) valid capacity when allocating a new
  memory region. Outside of that, new tests uncovered a small crop of
  lockdep reports.

  There is also some miscellaneous error path and leak fixups that are
  not urgent, but useful to cleanup now.

   - Fix alloc_free_mem_region()'s scan for address space, prevent false
     negative out-of-space events

   - Fix sleeping lock acquisition from CXL trace event (atomic context)

   - Fix put_device() like for the new CXL PMU driver

   - Fix wrong pointer freed on error path

   - Fixup several lockdep reports (missing lock hold) from new
     assertion in cxl_num_decoders_committed() and new tests"
