Subject: [PATCH] bcache: fix a regression of code compiling failure in debug.c

Git-commit: 33ec5dfe8f42aaf0163a16e2b450ab06f3a7f1f3

Patch-mainline: v5.13-rc1

References: bsc#1187357

The patch "bcache: remove PTR_CACHE" introduces a compiling failure in

debug.c with following error message,

  In file included from drivers/md/bcache/bcache.h:182:0,

                   from drivers/md/bcache/debug.c:9:

  drivers/md/bcache/debug.c: In function 'bch_btree_verify':

  drivers/md/bcache/debug.c:53:19: error: 'c' undeclared (first use in

  this function)

    bio_set_dev(bio, c->cache->bdev);

                     ^

This patch fixes the regression by replacing c->cache->bdev by b->c->

cache->bdev.
