Re: [PATCH v4] powerpc/powernv: add NULL check after kzalloc in opal_add_one_export

[Markus Elfring]

>>> Here needs a NULL check as kzalloc may fail returning NULL.

I find this wording potentially confusing.

* Such function calls will usually succeed to return a pointer.

* The desired memory allocation can fail.

* Please choose an imperative wording for the change description.


>>> Issue was found by coccinelle.

Please omit this line after the addition for the reference to the SmPL script.

I wonder about this tag because of requested changes for the shown patch approach.

I recommend to add the tag âFixesâ.

This seems to become challenging here.

I wonder why it was not directly tried in this patch version.


>>> v3->v4:

I suggest to apply a shorter version numbering format (without an arrow).
