Subject: [PATCH 31/45] tty: vt: use VESA blanking constants
Date: Thu, 18 Jan 2024 08:57:42 +0100 [thread overview]
Message-ID: <20240118075756.10541-32-jirislaby@kernel.org> (raw)
In-Reply-To: <20240118075756.10541-1-jirislaby@kernel.org>
There are VESA blanking constants defined in console.h already. So use
them in the console code instead of constant values.
