Commit: 1f83357fd15603ca3198889708db14ed141ddde9
Gitweb: http://git.linux-mips.org/g/ralf/linux/1f83357fd156
Branch: linux-2.6.33-stable

If CONFIG_SERIAL_8250 is set to m, the Loongson seria.ko module might get
unloaded while the serial driver modules are still loaded resulting in
stale references to the destroyed platform_device instance.

Anyway, platform devices should always be registered indicated what
devices are present, _not_ what drivers have been configured.
