From 33c0fb85b571b0f1bbdbf466e770eebeb29e6f41 Mon Sep 17 00:00:00 2001 From: Benjamin Tissoires Date: Sat, 8 Jun 2024 11:01:28 +0200 Subject: HID: bpf: make part of struct hid_device writable It is useful to change the name, the phys and/or the uniq of a struct hid_device during .rdesc_fixup(). For example, hid-uclogic.ko changes the uniq to store the firmware version to differentiate between 2 devices sharing the same PID. In the same way, changing the device name is useful when the device export 3 nodes, all with the same name.
