Subject: [PATCH] platform/x86: intel-vbtn: Allow switch events on Acer Switch Alpha 12
Date: Tue,  1 Dec 2020 14:57:27 +0100	[thread overview]
Message-ID: <20201201135727.212917-1-carlosg@gnome.org> (raw)

This 2-in-1 model (Product name: Switch SA5-271) features a SW_TABLET_MODE
that works as it would be expected, both when detaching the keyboard and
when folding it behind the tablet body.

It used to work until the introduction of the allow list at commit
8169bd3e6e193 ("platform/x86: intel-vbtn: Switch to an allow-list for
SW_TABLET_MODE reporting"). Add this model to it, so the Virtual Buttons
device announces the EV_SW features again.
