When compiling with -Wformat, clang emits the following warnings:

drivers/char/mem.c:775:16: error: format string is not a string literal (potentially insecure) [-Werror,-Wformat-security]
                              NULL, devlist[minor].name);
                                    ^~~~~~~~~~~~~~~~~~~

Use a string literal for the format string.
