Lockdep reported a lock inversion in one of the Qualcomm drivers and a closer review revealed that the changes had also broken the sysfs interface for at least three drivers. Note that a simple revert of the offending patches was not an option as some of the infrastructure that the old implementation relied on has also been removed.
