Subject[PATCH 4.14 129/165] b43legacy/leds: Ensure NUL-termination of LED name string
Date
4.14-stable review patch.  If anyone has any objections, please let me know.

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

From: Michael Buesch <m@bues.ch>

commit 4d77a89e3924b12f4a5628b21237e57ab4703866 upstream.

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