[PATCH 1/2] platform/x86: Fix ECO LED control on Toshiba Z830

[lkml@vorpal.se]

From: Arvid Norlander <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.
