Low-level control modules should statically set the owner field of the fpga_manager_ops struct to THIS_MODULE. Then, when the manager is registered using fpga_mgr_register(), the value is copied into the owner field of the fpga_manager struct (that contains the device context). In this way, the manager can later use it in fpga_mgr_get() to take the low-level module's refcount. To prevent races while unloading the low-level control module, fpga_mgr_get() and part of the fpga_mgr_unregister() methods are protected with a mutex. Other changes: move put_device() from __fpga_mgr_get() to fpga_mgr_get() and of_fpga_mgr_get() to improve code clarity.
