Subject: [PATCH v2 09/10] apparmor: test: Remove some casts which are no-longer required
Date: Thu, 13 May 2021 12:32:03 -0700	[thread overview]
Message-ID: <20210513193204.816681-9-davidgow@google.com> (raw)
In-Reply-To: <20210513193204.816681-1-davidgow@google.com>

With some of the stricter type checking in KUnit's EXPECT macros
removed, several casts in policy_unpack_test are no longer required.

Remove the unnecessary casts, making the conditions clearer.

This should be a no-op functionality wise, and while it depends on the
first couple of patches in this series, it's otherwise independent from
the others. I think this makes the test more readable, but if you
particularly dislike it, I'm happy to drop it.
