May I suggest that you make $subject:
"pinctrl: qcom: Extract chip specific LPASS LPI code"

I also have a hard time parsing this sentence.

How about simply:
Extract the chip specific SM8250 data from the LPASS LPI pinctrl driver
to allow reusing the common code in the addition of subsequent
platforms.
