Hi Vinod,

<snip>

This pull request appears to be missing some fixes for the clang warnings introduced by this series, which will break the build with CONFIG_WERROR=y:

https://lore.kernel.org/20231222-dma-xilinx-xdma-clang-fixes-v1-0-84a18ff184d2@kernel.org/

Cheers,
Nathan

Hi Nathan,

Sorry my bad to have missed these fixes, picking them now...

~Vinod

Hi Linus,

I have picked the fixes from Nathan and also found that with W=1 there were few other warnings reported, so picked/fixed them up as well. Added this to my test scripts so shouldnt be missed in the future.

I have merged this tag into my fixes branch and applied the changes on top. So the diff stat mentions older fixes already picked. I guess that wasnt a smart move, I should have picked changes on top of next.

Nevertheless I hope to not miss it again so please consider older pull request and then the below fixes request for v6.8-rc1
