From 73e4008ddddc84d5f2499c17012b340a0dae153e Mon Sep 17 00:00:00 2001 From: Nikolai Kondrashov Date: Fri, 6 Aug 2010 23:03:06 +0400 Subject: HID: allow resizing and replacing report descriptors Update hid_driver's report_fixup prototype to allow changing report descriptor size and/or returning completely different report descriptor. Update existing usage accordingly. This is to give more freedom in descriptor fixup and to allow having a whole fixed descriptor in the code for the sake of readability.

This patch adds a quirk which allows the HID driver to take over the input layer synchronization, and hence the control of the frame boundary.
