[PATCH 0/3] IPU3 ImgU driver parameter struct fixes

[Sakari Ailus <sakari.ailus@linux.intel.com>]

Hi all,

This set addresses parameter struct memory layout changes introduced by
seemingly innocent patches, and adds a sanity check for the struct size to
avoid this from happening again. This only touches the uAPI, not the
ipu3-abi.h that deals with ABI not visible in the driver uAPI. That should
be addressed as well going forward.

The first patch does not probably entirely fix the issues, but with the
second patch added, pahole agrees the struct memory layout is unchanged
from the previous state.

  Revert "staging: imgu: Address a compiler warning on alignment"
  staging: ipu3-imgu: Move alignment attribute to field
  staging: ipu3-imgu: Add a sanity check for the parameter struct size
