Subject: [PATCH 1/2] ACPI: Drop unnecessary label from acpi_bind_one()

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

The out_free label in acpi_bind_one() is only jumped to from one
place, so in fact it is not necessary, because the code below it
can be moved to that place directly.  Move that code and drop the
label.
