Subject: drivers/base: Platform notify needs to occur before drivers attach to the device
From: Brian Walsh <brian@xxxxxxxx>
The platform_notify call for Arm and PPC architectures needs to be called
before the driver attaches to the device. The problem only presents itself
when hotplugging certain devices while the driver is already loaded.
