From b7966a4d7be0a10329f03330390f4bdaf453d74a Mon Sep 17 00:00:00 2001 From: Benjamin Tissoires Date: Mon, 25 Feb 2013 11:31:47 +0100 Subject: [PATCH] HID: use hid_hw_wait() instead of direct call to usbhid This removes most of the dependencies between hid drivers and usbhid. The patch was constructed by replacing all occurences of usbhid_wait_io() by its hid_hw_wait() counterpart. Then, drivers not requiring USB_HID anymore have their USB_HID dependency cleaned in the Kconfig file. As of today, few drivers are still requiring an explicit USB layer dependency: * ntrig (a patch is on its way) * multitouch (one patch following and another on its way) * lenovo tpkbd * roccat * sony The last three are two deeply using direct calls to the usb subsystem to be able to be cleaned right now.
