Subject: [PATCH] arch: mips: lantiq: using strlcpy() instead of strncpy()
Date: Sun, 26 May 2013 15:51:49 +0800	[thread overview]
Message-ID: <51A1BF15.7070905@asianux.com> (raw)


'compatible' is used by strlen() in __of_device_is_compatible().

So for NUL terminated string, need always be sure of ended by zero.

'of_ids' is not a structure in "include/uapi/*", so not need initialize
all bytes, just use strlcpy() instead of strncpy().
