Subject: [PATCH 36/45] tty: vt: change consw::con_set_origin() return type
Date: Thu, 18 Jan 2024 08:57:47 +0100 [thread overview]
Message-ID: <20240118075756.10541-37-jirislaby@kernel.org> (raw)
In-Reply-To: <20240118075756.10541-1-jirislaby@kernel.org>
The return value of consw::con_set_origin() is only true/false, meaining
if vc->vc_origin is set to vc->vc_screenbuf or not.
So switch the type and returned values accordingly.
And document the hook.
