Subject: [PATCH] ACPI / platform: Drop unnecessary label

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

The create_dev label in acpi_create_platform_device() is not
necessary, because the if statement causing the jump to it to
happen may be rearranged to avoid that jump.

Rework the code accordingly (no functional changes should result
from that).

Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki@...el.com>

For 3.12, on top of linux-next.

Thanks,
Rafael
