UBSAN complains that we reach beyond the end of the log entry:
UBSAN: array-index-out-of-bounds in drivers/net/ethernet/meta/fbnic/fbnic_fw_log.c:94:50
index 71 is out of range for type 'char [*]'
Call Trace:
<TASK>
ubsan_epilogue+0x5/0x2b
fbnic_fw_log_write+0x120/0x960
fbnic_fw_parse_logs+0x161/0x210
We're just taking the address of the character after the array,
so this really seems like something that should be legal.
But whatever, easy enough to silence by doing direct pointer math.
Fixes: c2b93d6bec ("eth: fbnic: Create ring buffer for firmware logs")

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 reStructuredText 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.
