Subject: [PATCH 5.18 37/47] random: use proper return types on get_random_{int,long}_wait()
Date: Fri, 27 May 2022 10:50:17 +0200	[thread overview]
Message-ID: <20220527084807.437298401@linuxfoundation.org> (raw)
In-Reply-To: <20220527084801.223648383@linuxfoundation.org>

From: "Jason A. Donenfeld" <Jason@zx2c4.com>

commit 7c3a8a1db5e03d02cc0abb3357a84b8b326dfac3 upstream.

Before these were returning signed values, but the API is intended to be
used with unsigned values.
