The FPGA framework has a convention of using managed resource functions to allow parent drivers to manage the data structures allocated by the class drivers. They use an empty *_dev_release() function to satisfy the class driver. This is inconsistent with linux driver model. These changes remove the managed resource functions and populate the class dev_release callback functions. They also merge the create and register functions into a single register function for each of the fpga-mgr, fpga-region, and fpga-bridge class drivers. For more context, refer to this email thread: https://marc.info/?l=linux-fpga&m=162127412218557&w=2 I turned on the configs assocated with each of the modified files, but I must have been missing some dependencies, because not all of them compiled. I did a run-time test specifically with the dfl-fme infrastructure. This would have exercised the region, bridge, and fpga-mgr frameworks. Changelog v1 -> v2: - Restored devm_fpga_mgr_register() functionality to the fpga-mgr class driver, adapted for the combined create/register functionality. - All previous callers of devm_fpga_mgr_register() will continue to call devm_fpga_mgr_register(). - replaced unnecessary ternary operators in return statements with standard if conditions.
