I was trying to find this tree and it seems the MAINTAINERS file have
the wrong address:
DMA MAPPING HELPERS
M:      Marek Szyprowski <[email protected]>
R:      Robin Murphy <[email protected]>
L:      [email protected]
S:      Supported
W:      http://git.infradead.org/users/hch/dma-mapping.git
T:      git git://git.infradead.org/users/hch/dma-mapping.git

I believe the corret one is:
https://git.kernel.org/pub/scm/linux/kernel/git/mszyprowski/linux.git/

Thanks,
Mostafa
