What about the rest.. I checked SM8350 and SM8250 mtp ones are missing this.

From what I can see, SM8350 and SM8250 use qcom-snps-femto-v2 PHY rather than qcom-qusb2. So they should not be affected by this series. Shawn

So they should not be affected by this series. Right, somehow I seem to have overlooked that part :( I am applying this now, thanks -- ~Vinod
