[PATCH AUTOSEL 6.12 14/14] platform/x86: acer-wmi: Ignore AC events

[Sasha Levin <sashal@kernel.org>]

From: Armin Wolf <W_Armin@gmx.de>

[ Upstream commit f6bfa25c6665f8721421ea94fe506cc22f1d4b43 ]

On the Acer Swift SFG14-41, the events 8 - 1 and 8 - 0 are printed on
AC connect/disconnect. Ignore those events to avoid spamming the
kernel log with error messages.
