with W=1(this can't be reporduced with gcc 13.1.0):

drivers/md/raid1-10.c:117:25: error: casting from randomized structure
pointer type 'struct block_device *' to 'struct md_rdev *'
     117 |         struct md_rdev *rdev = (struct md_rdev *)bio->bi_bdev;
         |                                ^

Fix this by casting 'bio->bi_bdev' to 'void *', as it used to be.

Conflict:
  Commit 309dca30 ("block: store a block_device pointer in struct bio")
  changed "bi_disk" to "bi_bdev", and in commit 8295efbe ("md/raid1-10:
  factor out a helper to submit normal write"), "bi_bdev" was adapted to
  "bi_disk".
