I know: http://marc.info/?l=linux-kernel&m=136809709202740&w=2
I was expecting Mauro to fix it since his patches grew this out:
commit 7a623c039075e4ea21648d88133fafa6dcfd113d Author: Mauro Carvalho Chehab <mchehab@redhat.com> Date: Mon Apr 16 16:41:11 2012 -0300
edac: rewrite the sysfs code to use struct device
adds struct bus_type to struct mem_ctl_info which is dynamically allocated and that's why lockdep complains.
bus_register() needs to get a statically allocated struct bus_type as the rest of the kernel does it.
