From abe99210e0f624cea39f1dc375ba818b201c0d7f Mon Sep 17 00:00:00 2001 From: Mika Westerberg Date: Fri, 11 Jan 2013 22:08:09 +0100 Subject: [PATCH] ACPI / scan: Fix check of device_attach() return value. Since device_attach() returns 1 on success (a driver has been bound to the device), the check against its return value in acpi_bus_device_attach() should modified to take that into accout. Make it so. [rjw: Subject and changelog.] Signed-off-by: Mika Westerberg Signed-off-by: Rafael J.
