From 3b5f03c4e36c2756d3c10f93e4c829541bf1da28 Mon Sep 17 00:00:00 2001 From: David Herrmann Date: Sun, 5 May 2013 23:12:56 +0200 Subject: HID: wiimote: convert IR to module IR is the last piece that still is handled natively. This patch converts it into a sub-device module like all other sub-devices. It mainly moves code and doesn't change semantics. We also implicitly sync IR data on ir_to_input3 now so the explicit input_sync() calls are no longer needed.
