From 6fd182028c43baf1c7d017d52b0134ecadbdc447 Mon Sep 17 00:00:00 2001 From: Benjamin Tissoires Date: Sat, 8 Mar 2014 22:52:43 -0500 Subject: [PATCH] HID: remove hid_output_raw_report transport implementations Nobody calls hid_output_raw_report anymore, and nobody should. We can now remove the various implementation in the different transport drivers and the declarations.
