fpga: bridge: fix kernel-doc
Fix the following warnings issued by the kernel-doc script: drivers/fpga/fpga-bridge.c:99: warning: No description found for return value of 'of_fpga_bridge_get' drivers/fpga/fpga-bridge.c:163: warning: No description found for return value of 'fpga_bridges_enable' drivers/fpga/fpga-bridge.c:187: warning: No description found for return value of 'fpga_bridges_disable' drivers/fpga/fpga-bridge.c:238: warning: No description found for return value of 'of_fpga_bridge_get_to_list' drivers/fpga/fpga-bridge.c:268: warning: No description found for return value of 'fpga_bridge_get_to_list' - Extend the return description of of_fpga_bridge_get() to include the case when try_module_get() fails.
