Merge tag 'bitmap-for-5.19-rc1' of https://github.com/norov/linux

Pull bitmap updates from Yury Norov:

 - bitmap: optimize bitmap_weight() usage, from me

 - lib/bitmap.c make bitmap_print_bitmask_to_buf parseable, from Mauro
   Carvalho Chehab

 - include/linux/find: Fix documentation, from Anna-Maria Behnsen

 - bitmap: fix conversion from/to fix-sized arrays, from me

 - bitmap: Fix return values to be unsigned, from Kees Cook

It has been in linux-next for at least a week with no problems.
