On lines 3430-3434, bh has been assured to be non-null:
cn = get_journal_hash_dev(sb, journal->j_hash_table, blocknr);
if (!cn || !cn->bh) {
return ret;
}
bh = cn->bh;
Thus, the check of bh on line 3447 is unnecessary and can be removed.
Thank Andrew Morton for good advice.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
