Subject: [PATCH 00/28] iio: zero init stack with { } instead of memset()
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.
