Merge tag 'parisc-for-6.5-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux

Pull parisc architecture fixes from Helge Deller:
 "A bugfix in the LWS code, which used different lock words than the
  parisc lightweight spinlock checks. This inconsistency triggered false
  positives when the lightweight spinlock checks checked the locks of
  mutexes.

  The other patches are trivial cleanups and most of them fix sparse
  warnings.

  Summary:

   - Fix LWS code to use same lock words as for the parisc lightweight
     spinlocks

   - Use PTR_ERR_OR_ZERO() in pdt init code

   - Fix lots of sparse warnings"
