Subject: [PATCH 30/45] tty: vt: stop using -1 for blank mode in consw::con_blank()
Date: Thu, 18 Jan 2024 08:57:41 +0100	[thread overview]
Message-ID: <20240118075756.10541-31-jirislaby@kernel.org> (raw)
In-Reply-To: <20240118075756.10541-1-jirislaby@kernel.org>

-1 is the same as VESA_VSYNC_SUSPEND in all con_blank() implementations.
So we can remove this special case from vgacon now too.

Despite con_blank() of fbcon looks complicated, the "if
(!fbcon_is_inactive(vc, info))" branch is not taken as we set
"ops->graphics = 1;" few lines above. So what matters there (as in all
other blank implementations except vgacon) is if 'blank' is zero or not.
