Hi Miquel,

This series has fixes for the smatch warnings reported by Kbuild bot [1]
and also several cleanup patches based on my code observation.

I've only compile tested this series. So let's wait for Sadre/Sricharan to
give a tested-by tag to make sure I didn't mess up anything.

I reviewed all the patches, they look good to me. I'm waiting for the
tests. Please provide the output of nandbiterrs -i.

Thanks,

I tested the series on Qcom SDX55 based dev board, but it was broken already due
to commit <3fc92384b654> ("mtd: rawnand: qcom: Implement exec_op()").

I'm seeing a string of this error while the partitions were being enumerated:
qcom-nandc 1b30000.nand-controller: failed to copy last codeword

It just goes on...

Sadre, on what platform did you test 3fc92384b654? From a quick look, the BAM
DMA transactions are timing out.
