Subject: [PATCH AUTOSEL 5.4 109/175] platform/x86: intel-vbtn: Split keymap into buttons and switches parts
From: Hans de Goede <hdegoede@...hat.com>
[ Upstream commit f6ba524970c4b73b234bf41ecd6628f5803b1559 ]
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).
Fixes: de9647efeaa9 ("platform/x86: intel-vbtn: Only activate tablet mode switch on 2-in-1's")
