From: Thierry Reding <tred...@nvidia.com> Pass a pointer to the syscore_ops structure that was registered to the callbacks. This enables callbacks to act on instance data (syscore_ops can be embedded into other structures, and driver-specific data can be obtained using container_of()) rather than the current practice of relying on global variables.
