From 80d9ef8d40b2aa35c4a3483f5cf3549215187a7c Mon Sep 17 00:00:00 2001 From: Masahiro Yamada Date: Thu, 20 Nov 2014 21:20:32 +0900 Subject: lib: string: move strlcpy() to a common place Move strlcpy() definition from drivers/usb/gadget/ether.c to lib/string.c because it is a very useful function. Let's add the prototype to include/linux/string.h too.
