Jonathan mentioned recently that he would like to get away from using
memset() to zero-initialize stack memory in the IIO subsystem. And we
have it on good authority that initializing a struct or array with = { }
is the preferred way to do this in the kernel [1]. So here is a series
to take care of that.

1) Is it worth the churn?

2) Will this fail to initialize padding with some obscure compiler?

as of right now, the only two C compilers that are supported are
GCC >= 8.1, and Clang >= 13.0.1. If anyone even manages to get the
kernel

Well... I'm pretty sure parts of this would make it into -stable as a
dependency, or because AUTOSEL decides it is a bugfix. So..

GNU C                  4.9              gcc --version
Clang/LLVM (optional)  10.0.1           clang --version

Even though, what the kernel versions are you referring to? I am sure there
plenty of cases with {} there.
