From bc965a7f43d3fc37584f9c16c6d7a84a911a9d9c Mon Sep 17 00:00:00 2001 From: Russell King Date: Wed, 18 Jan 2006 09:54:29 +0000 Subject: [PATCH] [SERIAL] Fix serial8250 driver initialisation ordering Commit 7493a314cb83797ce612a577475aacaedc553fed changed the ordering of the registration of the platform device driver vs the 8250 drivers internal initialisation. This led to the probe function being called before the driver had finished its internal initialisation, causing mayhem. Revert the ordering change.
