This series fixes a handful of independent and mostly benign till now issues in the DTHEv2 driver which were flagged by bots and AI agents. Except for the fifth patch in this series which was found in an internal testing. The Sashiko review on DTHEv2 hashing driver patch series v5 pointed out some pre-existing issues which needed to be fixed [1]. One of the issues had already been flagged by kernel test bot and a fix sent on the list by Mert [2]. I included this patch in this series with minor edits. Then the Sashiko review page for [2] had more comments [3] Overall this resulted in a bunch of fixes patches which would have deviated the DTHEv2 hashing driver series had they been included with it. So I clubbed them together in a new patch series which is this.
