[dm-devel] [PATCH 14/19] floppy: use __bio_add_page for adding single page to bio

2023-03-29 Thread Johannes Thumshirn
The floppy code uses bio_add_page() to add a page to a newly created bio.
bio_add_page() can fail, but the return value is never checked.

Use __bio_add_page() as adding a single page to a newly created bio is
guaranteed to succeed.

This brings us a step closer to marking bio_add_page() as __must_check.
