Hello, This patch series fixes a (surprisingly large) number of drivers that don't zero-initialize structures passed to subdev pad operations. The rationale is explained in patch 1/3, which fixes the issue: while this doesn't cause any immediate problem, it leaves reserved fields uninitialized, and any future change of in-kernel APIs that make use of some of the reserved fields may introduce hard to catch breakages. Patches 2/3 and 3/3 are not strictly required to fix the problem, but they address coding style consistency issues that bothered me when developing 1/3.
