#     misc: ocxl: fix possible double free in ocxl_file_register_afu
#     
#     info_release() will be called in device_unregister() when info->dev's
#     reference count is 0. So there is no need to call ocxl_afu_put() and
#     kfree() again.
#     
#     Fix this by adding free_minor() and return to err_unregister error path.
#     
#     Fixes: 75ca758adbaf ("ocxl: Create a clear delineation between ocxl backend & frontend")
