Subject: [PATCH 1/2] platform/x86: Fix ECO LED control on Toshiba Z830
Date: Sun, 21 Aug 2022 22:08:21 +0200	[thread overview]
Message-ID: <20220821200821.1837460-2-lkml@vorpal.se> (raw)
In-Reply-To: <20220821200821.1837460-1-lkml@vorpal.se>

The toshiba_acpi driver checks for TOS_INPUT_DATA_ERROR and tries a
different format. On the Z830 the error returned is TOS_NOT_SUPPORTED
though the different format still works. Allow either error.
