From cafebc058bf86e63fff5354864781d3de11e41d3 Mon Sep 17 00:00:00 2001 From: Benjamin Tissoires Date: Wed, 5 Feb 2014 16:33:22 -0500 Subject: HID: remove hid_get_raw_report in struct hid_device dev->hid_get_raw_report(X) and hid_hw_raw_request(X, HID_REQ_GET_REPORT) are strictly equivalent. Switch the hid subsystem to the hid_hw notation and remove the field .hid_get_raw_report in struct hid_device.
