From 3f1f8303b6e0be751d7a7c55031c8ab840ed5c1a Mon Sep 17 00:00:00 2001

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.
