Bitmap search functions return a value greater than or equal to nbits when
no suitable bits are found. bitmap_find_next_zero_area_off() is an
exception: it returns a value greater than nbits.

Align the function with the rest of the API and adjust the affected callers
accordingly.

Patches 1-4 are sent only to their respective maintainers and mailing
lists. Patch 5 and the cover letter are sent to all recipients.

On top of -next. I plan to carry the series with bitmap-for-next.

  ARM: dma-mapping: Treat bitmap size as allocation failure
  powerpc/msi: Treat bitmap size as allocation failure
  crypto: ccp: Treat bitmap size as allocation failure
  media: s5p-mfc: Treat bitmap size as allocation failure
  bitmap: Return size when no zero area is found
