From 0d2689c0f054f6a8bf3115d6386bd9c2d65dc44b Mon Sep 17 00:00:00 2001 From: Benjamin Tissoires Date: Fri, 7 Jan 2011 23:44:32 +0100 Subject: HID: add feature_mapping callback Currently hid doesn't export the features it knows to the specific modules. Some information can be really important in such features: MosArt and Cypress devices are by default not in a multitouch mode. We have to send the value 2 on the right feature. This patch exports to the module the features report so they can find the right feature to set up the correct mode.
