+Subject: [PATCH] media: rc: ir-rc6-decoder: enable toggle bit for Kathrein
+ RCU-676 remote
+
+The Kathrein RCU-676 remote uses the 32-bit rc6 protocol and toggles
+bit 15 (0x8000) on repeated button presses, like MCE remotes.
+
+Add it's customer code 0x80460000 to the 32-bit rc6 toggle
+handling code to get proper scancodes and toggle reports.
