Are you saying the code isn't broken _because_ a static tool analyser did not see anything wrong here?

You are partially right, but will the staggering lack of comments in the caam driver be fixed by duplicating a cascade of three ifs into english?

If you have the new error codes please send them to me for an update.

You basically ask me to agree that if there are no _documented_ error codes between 0x8 and 0xf then I should trust that they will never come up on a 4 bit field.
Do you want me to drop the patch and pretend there is nothing to see?
