fpga: bridge: change api, don't use drvdata
Change fpga_bridge_register to not set drvdata. This is to support the case where a PCIe device can have more than one bridge. Add API functions to create/free the fpga bridge struct. Change fpga_bridge_register/unregister to take FPGA bridge struct as the only parameter. struct fpga_bridge *fpga_bridge_create(struct device *dev, const char *name, const struct fpga_bridge_ops *br_ops, void *priv); void fpga_bridge_free(struct fpga_bridge *br); int fpga_bridge_register(struct fpga_bridge *br); void fpga_bridge_unregister(struct fpga_bridge *br); Update the drivers that call fpga_bridge_register with the new API.
