Johan Hovold ae62cf5eb2 staging: greybus: loopback_test: fix potential path truncations 
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.
