[kbuild test robot <fengguang.wu@intel.com>]

drivers/staging/fpga/fpga-mgr.c:46:5: sparse: symbol 'fpga_mgr_low_level_state' was not declared. Should it be static?
drivers/staging/fpga/fpga-mgr.c:324:30: sparse: symbol 'fpga_mgr_groups' was not declared. Should it be static?
drivers/staging/fpga/fpga-mgr.c:365:25: sparse: symbol 'fpga_mgr_dev_pm_ops' was not declared. Should it be static?
