Subject: [PATCH] kdb: include kdb_private.h for function prototypes

From: Arnd Bergmann <arnd@...db.de>

The kdb_kbd_cleanup_state() is called from another file through
the kdb_private.h file, but that is not included before the
definition, causing a W=1 warning:

kernel/debug/kdb/kdb_keyboard.c:198:6: error: no previous prototype for 'kdb_kbd_cleanup_state' [-Werror=missing-prototypes]
