+Subject: [PATCH] lircd: Remove use of functions killed in kernel 4.8.0
+
+From 4.8.0 the kernel no longer supports LIRC_NOTIFY_DECODE,
+LIRC_SETUP_START/LIRC_SETUP_END and several constants related
+to initiating filters. Remove corresponding calls from lircd.
+
+[baruch: move DRVCTL_NOTIFY_DECODE into lircd.cpp]
