From: Shenghui Wang <shhuiw@xxxxxxxxxxx>
We have struct cached_dev allocated by kzalloc in register_bcache(), which
initializes all the fields of cached_dev with 0s. And commit ce4c3e19e520
("bcache: Replace bch_read_string_list() by __sysfs_match_string()") has
remove the string "default".
Update the comment.
