Merge tag 'for-5.20/parisc-1' of git://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux
Pull parisc updates from Helge Deller: "One real bugfix to change the io_pgetevents_time64() syscall to use the compat implementation when running in compat mode, otherwise the signed int32 parameters min_nr and nr will be incorrectly handled as unsigned int64 values. Other than that just small cleanups: - hardware database housekeeping and proper /proc/iomem output - add proper function exit code if probe functions fail - drop stale variables (pa_swapper_pg_lock) - drop unneccessary zero-initializations - typo fixes in comments" * tag 'for-5.20/parisc-1' of git://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux: Input: gscps2 - check return value of ioremap() in gscps2_probe() parisc: io_pgetevents_time64() needs compat syscall in 32-bit compat mode parisc: Drop zero variable initialisations in mm/init.c parisc: Do not initialise statics to 0 parisc: Check the return value of ioremap() in lba_driver_probe() parisc: Drop pa_swapper_pg_lock spinlock parisc: Fix comment typo in fault.c parisc: Fix device names in /proc/iomem parisc: Clean up names in hardware database
