Subject: [GIT PULL] parisc architecture fixes for v6.5-rc6

Hi Linus,

please pull some more fixes for the parisc architecture for kernel 6.5-rc6.

This patchset includes 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.

Thanks!
Helge
