Subject: [PATCH 5/5] ACPI: Clean up error code path in acpi_unbind_one()
Date: Tue, 06 Aug 2013 02:28:36 +0200	[thread overview]
Message-ID: <7329028.7Z1dZAAkTZ@vostro.rjw.lan> (raw)
In-Reply-To: <3015032.qfOqgEVZKP@vostro.rjw.lan>

From: Rafael J. Wysocki <rafael.j.wysocki@intel.com>

The error code path in acpi_unbind_one() is unnecessarily complicated
(in particular, the err label is not really necessary) and the error
message printed by it is inaccurate (there's nothing called
'acpi_handle' in that function), so clean up those things.
