drm/tegra: Remove gratuitous pad field
The version of the drm_tegra_submit structure that was merged all the way back in 3.10 contains a pad field that was originally intended to properly pad the following __u64 field. Unfortunately it seems like a different field was dropped during review that caused this padding to become unnecessary, but the pad field wasn't removed at that time. One possible side-effect of this is that since the __u64 following the pad is now no longer properly aligned, the compiler may (or may not) introduce padding itself, which results in no predictable ABI. Rectify this by removing the pad field so that all fields are again naturally aligned. Technically this is breaking existing userspace ABI, but given that there aren't any (released) userspace drivers that make use of this yet, the fallout should be minimal. Fixes: d43f81cbaf43 ("drm/tegra: Add gr2d device") Cc: <stable@vger.kernel.org> # 3.10 Signed-off-by: Thierry Reding <treding@nvidia.com>
