From: Tomasz Unger <tomasz.unger@yahoo.pl>

Replace strcpy() with strscpy() which limits the copy to the size of
the destination buffer. Since fw_info->fw_name is an array with a fixed, declared size, the
two-argument variant of strscpy() is used - the compiler deduces
the buffer size automatically.

This is a defensive cleanup replacing the deprecated strcpy()
with the preferred strscpy().

And ignored the rest?

<form letter>
This is a friendly reminder during the review process.

It looks like you received a tag and forgot to add it.

If you do not know the process, here is a short explanation:
Please add Acked-by/Reviewed-by/Tested-by tags when posting new versions
of patchset, under or above your Signed-off-by tag, unless patch changed
significantly (e.g. new properties added to the DT bindings). Tag is
"received", when provided in a message replied to you on the mailing
list. Tools like b4 can help here. However, there's no need to repost
patches *only* to add the tags. The upstream maintainer will do that for
tags received on the version they apply.

Please read:
https://elixir.bootlin.com/linux/v6.12-rc3/source/Documentation/process/submitting-patches.rst#L577

If a tag was not added on purpose, please state why and what changed.
