Subject: [PATCH 08/17] tty: goldfish: drop unneeded temporary variables
Date: Tue, 21 Nov 2023 10:22:49 +0100 [thread overview]
Message-ID: <20231121092258.9334-9-jirislaby@kernel.org> (raw)
In-Reply-To: <20231121092258.9334-1-jirislaby@kernel.org>
We can pass 'buf' directly to goldfish_tty_rw() using simple (unsigned
long) cast. There is no need to obfuscate the code by another variable
with double casts.
