From 9ebf3d7687192923e3d44fdbcd8d9f8375053fb8 Mon Sep 17 00:00:00 2001 From: Henrik Rydberg Date: Mon, 30 Jul 2012 13:28:18 +0200 Subject: HID: Add an input configured notification callback A hid device may create several input devices, and a driver may need to prepare or finalize the configuration per input device. Currently, there is no sane way for a driver to know when a device has been configured. This patch adds a callback providing that information.

Increase the limit to 256. This adds another kilobyte of memory per report.
