Subject: [PATCH 03/10] tty: sysrq: switch the rest of keys to u8
Date: Wed, 12 Jul 2023 10:18:04 +0200	[thread overview]
Message-ID: <20230712081811.29004-4-jirislaby@kernel.org> (raw)
In-Reply-To: <20230712081811.29004-1-jirislaby@kernel.org>

Propagate u8 more from the bottom to the interface, so that sysrq
callers (usually drivers) see that u8 is expected.
