kfree is a noop if passed a null pointer.
So you can just add the missing kfree's to fix this.

as far as I know, most codes in the kernel are in the same style as this
patch, but if you really prefer to do in the way you described I can send
a new version.
Let me know.

I prefer the simpler variant.
Please redo.

strbuf will be uninitialized if the iommu allocation fails. I don't have
a particular preference for how to fix this but tend to dislike initial
assignment with NULL because it hides other control flow issues.

Sorry I didn't notice strbuf will be uninitialized here. But if we don't
initially assign a NULL value to strbuf, I cannot find a way to handle it
besides the first version patch. Did you have any suggestions? For me, I like
the first version.

Two thoughts...
1 - just use a goto target for the iommu allocation failure and make
that skip the strbuf free call. The others use the existing
fatal_memory_error label.
2 - Move the strbuf kzalloc up 2 lines so that it occurs before the test
for iommu.
2b - In case (2) above the failure test could be changed to
if (!iommu || !strbuf)
to remove duplication of goto.
I'd probably go for 2/2b to address Sam's initial comment.

Richard

this looks ugly. If we do in this way, why not version 1?

I will send a new version by using this solution.
