[PATCH AUTOSEL 5.4 02/15] platform/x86: asus-nb-wmi: Revert "Do not load on Asus T100TA and T200TA"

[Sasha Levin]

From: Hans de Goede <hdegoede@xxxxxxxxxx>

[ Upstream commit aab9e7896ec98b2a6b4eeeed71cc666776bb8def ]

The WMI INIT method on for some reason turns on the camera LED on these
2-in-1s, without the WMI interface allowing further control over the LED.

To fix this commit b5f7311d3a2e ("platform/x86: asus-nb-wmi: Do not load
on Asus T100TA and T200TA") added a blacklist with these 2 models on it
since the WMI driver did not add any extra functionality to these models.

Recently I've been working on making more 2-in-1 models report their
tablet-mode (SW_TABLET_MODE) to userspace; and I've found that these 2
Asus models report this through WMI. This commit reverts the adding
of the blacklist, so that the Asus WMI driver can be used on these
models to report their tablet-mode.

Note, not calling INIT is also not an option, because then we will not
receive events when the tablet-mode changes. So the LED issue will need
to be fixed somewhere else entirely.
