[PATCH 0/3] media: Zero-initialize structures passed to subdev pad ops

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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.

Laurent Pinchart (3):
  media: Zero-initialize all structures passed to subdev pad operations
  media: Prefer designated initializers over memset for subdev pad ops
  media: USe designated initializers for all subdev pad ops
