Check the printk format string against the matching arguments. We have
this type of checking in the v3 code since ages, but v2 will happily compile any code with bogus printk format strings and/or parameters. This can cause real bugs and at least needs to emit a warning, if not an error. Go with a warning for now since most of the flagged format strings are wrong but harmless in a 32-bit x86 environment.
