Subject: [PATCH 09/37] smccc: Cast arguments to unsigned long
Date: Wed, 15 Jul 2020 19:44:10 +0100 [thread overview]
Message-ID: <20200715184438.1390996-10-ascull@google.com> (raw)
In-Reply-To: <20200715184438.1390996-1-ascull@google.com>
To avoid warning about implicit casting, make the casting explicit. This
allows, for example, pointers to be used as arguments.
