'dmaengine_prep_dma_cyclic()' does not return an error pointer, so the test
can be simplified to be more consistent.

The change looks correct in principle. It would be good to automate looking
for other instances of this bug. How did you find it? Do you have e.g. a
coccinelle script or did you just stumble over the issue by accident?
There is one problem with your patch:

The serial driver is for the sirf platform, which uses the sirf-dma
dmaengine driver, and that particular driver has an incorrect
dma_prep_cyclic implementation, so I think we also need this fix:

I'm working on collecting this information in a more general way. It is
complicated by the fact that there are some functions that have the same
names but different behaviors, and I want to be clear about when that is
an issue. There are nevertheless limits to the accuracy that can be
obtained with Coccinelle, because Coccinelle doesn't take values into
account. Sometimes a variable is initialized to NULL, just to have a
starting value, but in practice the only way to reach an error return is
via conditionals that have the effect of ensuring that the value is
ERR_PTR. So at least the cases that are reported as being able to return
both NULL and ERR_PTR will need some careful checking.

Hi,
You can have an idea of the strategy used in this post:
https://lkml.org/lkml/2016/11/1/388
Julia is currently working on a more complete strategy in order to find
such issues.
In the meantime, if you want, I can send the coccinelle scripts used.
Best regards,
CJ

I have a set of reports in the files listed below. If anyone wants to
take a look at them, I would be happy to send them along. It is
definitely possible that the list contains false positives.
