Seems like gcc didn't catch this when I compiled locally. Normally, this would be fixed if we placed braces around the individual initialization blocks, that is, say { struct device_node *qmgrs __free(device_node) = of_get_child_by_name(node, "qmgrs"); ... } That would make the code look a lot more dirty though and is purely unnecessary. So I'd say I'd drop this patch and do a v2 with the remaining two patches. Thoughts? There's also some stuff with classes but that too is not really worth doing because the code will end up looking very ugly. Thanks ^ permalink raw reply [flat|nested] 6+ messages in thread

Please include the patch in such a message so that one can see everything at once. I'm not sure it's necessary to show all the error messages either.

FWIW, you may notice this as you do more conversions. The fact that GCC does not warn at all is a GCC bug as far as I am aware (i.e., clang's error is correct): https://gcc.gnu.org/bugzilla/show_bug.cgi?id=91951 which has come up in other places: https://lore.kernel.org/20240425174732.GA270911@dev-arch.thelio-3990X/ Cheers, Nathan ^ permalink raw reply [flat|nested] 6+ messages in thread

Independent of all this, it's not a good idea form a readability point of view to mix automated and manual cleanup. So in cases like this where you want to do scope based cleanup, use separate functions that have appropriately defined scope (or brackets for the really minor cases). Here, you may just be able to push the device_node get into knav_queue_setup_regions() for example.
