+Subject: dib0700: fix nec repeat handling
+MIME-Version: 1.0

+
+commit ba13e98f2cebd55a3744c5ffaa08f9dca73bf521 upstream.
+
+When receiving a nec repeat, ensure the correct scancode is repeated
+rather than a random value from the stack.  This removes the need for
+the bogus uninitialized_var() and also fixes the warnings:
+
+    drivers/media/usb/dvb-usb/dib0700_core.c: In function ‘dib0700_rc_urb_completion’:
+    drivers/media/usb/dvb-usb/dib0700_core.c:679: warning: ‘protocol’ may be used uninitialized in this function
+
+[sean addon: So after writing the patch and submitting it, I've bought the
+             hardware on ebay. Without this patch you get random scancodes
+             on nec repeats, which the patch indeed fixes.]
