+Subject: [PATCH] fix auto-sense in lirc_rpi driver
+
+On a Raspberry Pi 2, the lirc_rpi driver might receive spurious
+interrupts and change it's low-active / high-active setting.
+When this happens, the IR remote control stops working.
+
+This patch disables this auto-detection if the 'sense' parameter
+was set in the device tree, making the driver robust to such
+spurious interrupts.
