Subject: [PATCH] media: rc: ir-rc6-decoder: enable toggle bit for Kathrein
RCU-676 remote
Git-commit: 85e4af0a7ae2f146769b7475ae531bf8a3f3afb4
References: git-fixes
Patch-mainline: v4.20-rc1
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.
