Apologies for the incomplete list.

I had re-based this patch on top of "for-next" branch of the kernel 
https://git.kernel.org/pub/scm/linux/kernel/git/qcom/linux.git.

My git describe shows something like as follows

qcom-arm64-for-6.1-173-gd92bd73

Also the ./script/maintainers.pl gives the below output

Souradeep Chowdhury <quic_schowdhu at quicinc.com> (maintainer:DCC QTI 
DRIVER,in file)
Andy Gross <agross at kernel.org> (maintainer:ARM/QUALCOMM SUPPORT)
Bjorn Andersson <andersson at kernel.org> (maintainer:ARM/QUALCOMM SUPPORT)
Konrad Dybcio <konrad.dybcio at somainline.org> (reviewer:ARM/QUALCOMM SUPPORT)
Rob Herring <robh+dt at kernel.org> (maintainer:OPEN FIRMWARE AND FLATTENED 
DEVICE TREE BINDINGS)
Krzysztof Kozlowski <krzysztof.kozlowski+dt at linaro.org> (maintainer:OPEN 
FIRMWARE AND FLATTENED DEVICE TREE BINDINGS)
linux-arm-msm at vger.kernel.org (open list:DCC QTI DRIVER)
devicetree at vger.kernel.org (open list:OPEN FIRMWARE AND FLATTENED DEVICE 
TREE BINDINGS)
linux-kernel at vger.kernel.org (open list)

Will send out the next version accordingly, let me know in case of any 
further concerns.
