Is this equivalent code ?

Its also a bit confusing to me that the next patch adds a .available 
field to the qcom_scm struct.

I see where you do get drvdata but I haven't managed to find in the 
series where the data gets set - haven't asked an LLM either - I think 
the logic to associate the scm pointer and get it should live together 
in one patch so that the logic is easier to find and reason about.
