It is, of course, up to Felipe. ...but in my opinion this is the
wrong change and instead we should be deleting the SoC-specific
strings (msm8996, msm8998, sdm845) from this file because they don't
buy us anything. To explain how it works:
1. Device tree should have both the "SoC-specific" and generic
"qcom,dwc3" strings. Only the "qcom,dwc3" will actually be used but
the SoC-specific string is there so if we find a case later where we
need to handle a SoC-specific quirk then it'll already be there.
2. Bindings should have both the "SoC-specific" and generic
"qcom,dwc3" strings. The binding is describing what's in the device
tree.
3. Until we have a SoC-specific quirk to handle, we _don't_ need to
add the SoC-specific string to the driver itself.

Can i remove this patch { .compatible = "qcom,sc7180-dwc3" }, in the
next version of this series ?
