Subject: [PATCH] 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'

The patch is based on top of 38dbcd697770 ("fpga: bridge: fix kernel-doc parameter description").
