Subject: [PATCH 02/11] tty: vt: drop get_vc_uniscr()
Date: Thu, 12 Jan 2023 09:01:27 +0100 [thread overview]
Message-ID: <20230112080136.4929-2-jirislaby@kernel.org> (raw)
In-Reply-To: <20230112080136.4929-1-jirislaby@kernel.org>
Its definition depends on the NO_VC_UNI_SCREEN macro. But that is never
defined, so remove all this completely. I.e. expand the macro to
vc->vc_uni_screen everywhere.
