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.
No, in the presence of a structure initializer fields not explicitly initialized will be set to 0 by the compiler.
really? do all C compilers have such behavior ?
Yes, all conforming to the C standard.
Thanks.
