Re: [PATCH] powerpc/iommu/debug: Remove redundant NULL check

It looks like the kernel test robot also reported this:
"[PATCH] powerpc/iommu/debug: fix ifnullfree.cocci warnings"
Weirdly I don't see it in patchwork.

I'm not sure which one mpe will want to take but either would do.

Fix the following coccicheck warnings:

./fs/io_uring.c:5989:4-9: WARNING: NULL check before some freeing
functions is not needed.

(Also, while unimportant, that's technically not the error you fix here
as it's for a different file!)

This looks correct to me, and matches the description of debugfs_remove
in Documentation/filesystems/debugfs.rst.

If you have a number of similar fixes it might be helpful to do them in
a single bigger patch, but I'm not sure if coccicheck reports much else
as I don't have coccinelle installed at the moment.
