From 206342541fc887ae919774a43942dc883161fece Mon Sep 17 00:00:00 2001 From: Benjamin Tissoires Date: Mon, 4 May 2026 10:47:23 +0200 Subject: HID: core: introduce hid_safe_input_report() hid_input_report() is used in too many places to have a commit that doesn't cross subsystem borders. Instead of changing the API, introduce a new one when things matters in the transport layers: - usbhid - i2chid This effectively revert to the old behavior for those two transport layers.
