From 58818a77cd415e2f76607749de5a1ff24e58cefe Mon Sep 17 00:00:00 2001 From: Dimitris Papastamos Date: Mon, 6 Dec 2010 15:42:17 +0000 Subject: [PATCH] ASoC: soc-core: Replace use of strncpy() with strlcpy() By using strncpy() if the source string does not have a null byte in the first n bytes, then the destination string is not null-terminated. This can be fixed in a two-step process by manually null-terminating the array after the use of strncpy() or by using strlcpy().
