Subject: ACPI: thinkpad-acpi: silence _sta warning
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=013c40e457ac573b29daa0e369c2ba6729c23557;p=linux-beck.git

ACPI: thinkpad-acpi: silence _sta warning

When both CONFIG_THINKPAD_ACPI_DOCK and CONFIG_THINKPAD_ACPI_BAY are
undefined, _sta is not used and that causes a gcc warning.  Fix it
(and I think this is a regression, I am pretty sure I fixed this once
before, sorry about that).

Issue reported by: Pritt Laes.
