+Subject: [PATCH] Use strcmp instead of sizeof on char* string
+
+This bug was detected by the clang warning:
+libsocketcan.c:384:16: warning: argument to 'sizeof' in 'strncmp' call
+is the same expression as the source; did you mean to provide an
+explicit length? [-Wsizeof-pointer-memaccess]
+sizeof(name)) != 0)
+~~~~~~~^~~~~~
