From 1abf25a25b86dcfe28d243a5af71bd1c9d6de1ef Mon Sep 17 00:00:00 2001 From: Mika Westerberg Date: Tue, 9 Jun 2015 12:17:07 +0300 Subject: [PATCH] mfd: lpc_ich: Assign subdevice ids automatically Using -1 as platform device id means that the platform driver core will not assign any id to the device (the device name will not have id at all). This results problems on systems that have multiple PCHs (Platform Controller HUBs) because all of them also include their own copy of LPC device. All the subsequent device creations will fail because there already exists platform device with the same name. Fix this by passing PLATFORM_DEVID_AUTO as platform device id. This makes the platform device core to allocate new ids automatically.
