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

Hi Jiapeng Chong, [off-list ref] writes:

Fix the following coccicheck warnings:

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

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.
