5.10-stable review patch. If anyone has any objections, please let me know.
------------------
From: Denis Benato <benato.denis96@xxxxxxxxx>
[ Upstream commit 06ae5afce8cc1f7621cc5c7751e449ce20d68af7 ]
In the function asus_kbd_set_report the parameter buf is read-only
as it gets copied in a memory portion suitable for USB transfer,
but the parameter is not marked as const: add the missing const and mark
const immutable buffers passed to that function.
