Regarding the fixes tag, how did you actually get to my patch?
While it's possible that it caused the regression, it did not
introduce the ERR_PTR() usage that was already there in
5c9f8c2dbdbe ("dmaengine: qcom: Add ADM driver").

Maybe there is another bug that needs to be addressed in this
driver?
