This seems like churn on its own, Jonathan may not apply it.

Also, I feel like just putting checkpatch warnings directly into the commit message is bad practice. Much better if it were "Add a blank line after variable declarations per checkpatch warning."

True. This highlights a broader point. When making
a number of cleanups to a driver (and I am generally more willing to take those than many maintainers) please group them into a little patch series with a cover letter.

If this is one of a set and overall the seem worthwhile I might pick them up. Plus this driver is pretty aged so there are other quality of code / modernization things that will make much more of an impact than just this blank line. Take a look at some of the other similar cleanup series on the IIO list and see what makes sense here. To give you a starter, dev_err_probe() and checking which prints are actually useful + stopping the driver rejecting Device tree falllback compatibles because of the hard fail on a device ID mismatch.

Fully agree with this. We really don't care what the print is, just what is being improved and why.

Thanks

Hi Jonathan and Joshua,

Thank you for the advice. I will create a new patch series with a cover letter for this hts221 driver accordingly based on your feedback.
