[PATCH 3.16 122/328] b43legacy/leds: Ensure NUL-termination of LED name string

[Ben Hutchings]

3.16.62-rc1 review patch.  If anyone has any objections, please let me know.

------------------

From: Michael BÃsch <m@xxxxxxx>

commit 4d77a89e3924b12f4a5628b21237e57ab4703866 upstream.

strncpy might not NUL-terminate the string, if the name equals the buffer size.
Use strlcpy instead.
