+Subject: kobject: Replace strncpy with memcpy
+
+From: Guenter Roeck <linux@roeck-us.net>
+
+commit 77d2a24b6107bd9b3bf2403a65c1428a9da83dd0 upstream.
+
+gcc 8.1.0 complains:
+
+lib/kobject.c:128:3: warning:
+       'strncpy' output truncated before terminating nul copying as many
+       bytes from a string as its length [-Wstringop-truncation]
+lib/kobject.c: In function 'kobject_get_path':
+lib/kobject.c:125:13: note: length computed here
+
+Using strncpy() is indeed less than perfect since the length of data to
+be copied has already been determined with strlen(). Replace strncpy()
+with memcpy() to address the warning and optimize the code a little.
