commit ae62cf5eb2792d9a818c2d93728ed92119357017 upstream.
Newer GCC warns about possible truncations of two generated path names as
we're concatenating the configurable sysfs and debugfs path prefixes
with a filename and placing the results in buffers of the same size as
the maximum length of the prefixes.
snprintf(d->name, MAX_STR_LEN, "gb_loopback%u", dev_id);
snprintf(d->sysfs_entry, MAX_SYSFS_PATH, "%s%s/",
t->sysfs_prefix, d->name);
snprintf(d->debugfs_entry, MAX_SYSFS_PATH, "%sraw_latency_%s",
t->debugfs_prefix, d->name);
Fix this by separating the maximum path length from the maximum prefix
length and reducing the latter enough to fit the generated strings.
Note that we also need to reduce the device-name buffer size as GCC
isn't smart enough to figure out that we ever only used MAX_STR_LEN
bytes of it.

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.
