An uninitialized variable @data.have_async may be used as analyzed by the following inline comments:

static int __device_attach(struct device *dev, bool allow_async) { // if @allow_async is true.

... struct device_attach_data data = { .dev = dev, .check_async = allow_async, .want_async = false, }; // @data.have_async is not initialized.

As Dmitry said, this is incorrect, please fix your broken code analysis tool, it is obviously not working properly :(

thanks,
