Myeonghun Pak e7e12b4cc0 char: xilinx_hwicap: unregister class on init errors ... hwicap_module_init() registers icap_class before reserving the character-device region and registering the platform driver. If either of those later steps fails, the init path must undo the successful class registration before returning an error. Route the chrdev registration failure through a class unwind label, and let the platform-driver registration failure fall through the existing chrdev unwind before unregistering the class. The normal module exit path is unchanged. This issue was identified during our ongoing static-analysis research while reviewing kernel code.
