I asked last time and there was just partial improvement, so let me be
clear: you must rebase on latest kernel and use scripts/get_maintainers.pl.
I am repeating myself, which should not be actually needed... but then
maybe my comment was not accurate? If so, please post the output of `git
describe` and `scripts/get_maintainers.pl __on_your_patches__` and let's
go line by line...

odd indentation. Use 4 spaces for example indentation.

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@quicinc.com> (maintainer:DCC QTI
DRIVER,in file)
Andy Gross <agross@kernel.org> (maintainer:ARM/QUALCOMM SUPPORT)
Bjorn Andersson <andersson@kernel.org> (maintainer:ARM/QUALCOMM SUPPORT)
Konrad Dybcio <konrad.dybcio@somainline.org> (reviewer:ARM/QUALCOMM SUPPORT)
Rob Herring <robh+dt@kernel.org> (maintainer:OPEN FIRMWARE AND FLATTENED
DEVICE TREE BINDINGS)
Krzysztof Kozlowski <krzysztof.kozlowski+dt@linaro.org> (maintainer:OPEN
FIRMWARE AND FLATTENED DEVICE TREE BINDINGS)
linux-arm-msm@vger.kernel.org (open list:DCC QTI DRIVER)
devicetree@vger.kernel.org (open list:OPEN FIRMWARE AND FLATTENED DEVICE
TREE BINDINGS)
linux-kernel@vger.kernel.org (open list)
Will send out the next version accordingly, let me know in case of any
further concerns.
