v4l2-compat-ioctl32: fix struct v4l2_event32 alignment
Union v4l2_event::u is aligned to 8 bytes on arm32. On arm64 v4l2_event32::u
is aligned to 4 bytes. As a result structures v4l2_event and v4l2_event32 have
different sizes and VIDOC_DQEVENT ioctl does not work from arm32 apps running
on arm64 kernel. The patch fixes it.
