Great catch! I am going to do the following change in v6:

--- a/kernel/printk/printk.c
+++ b/kernel/printk/printk.c
@@ -359,11 +359,10 @@ static void __up_console_sem(unsigned long ip)
 static int console_locked;
 
 /*
- *	Array of consoles built from command line options (console=)
+ * Array of consoles preferred via the command line, or by
+ * some platform-specific code, e.g. SPCR, or DT.
  */
-
 #define MAX_PREFERRED_CONSOLES 8
-
 static struct preferred_console preferred_consoles[MAX_PREFERRED_CONSOLES];
 
 static int preferred_console = -1;
