From f6ba524970c4b73b234bf41ecd6628f5803b1559 Mon Sep 17 00:00:00 2001 From: Hans de Goede Date: Sat, 2 May 2020 20:29:48 +0200 Subject: [PATCH] platform/x86: intel-vbtn: Split keymap into buttons and switches parts Split the sparse keymap into 2 separate keymaps, a buttons and a switches keymap and combine the 2 to a single map again in intel_vbtn_input_setup(). This is a preparation patch for not telling userspace that we have switches when we do not have them (and for doing the same for the buttons).
