Subject: [PATCH v3 2/7] dummycon: Implement struct consw.con_unblank
Date: Fri, 23 Oct 2026 15:16:12 +0200 [thread overview]
Message-ID: <20261023132448.115747-3-tzimmermann@suse.de> (raw)
In-Reply-To: <20261023132448.115747-1-tzimmermann@suse.de>
Implement con_unblank from struct consw as a duplicate of con_blank.
As dummycon does not do anything, the implementation only returns
true or false to trigger a redraw (or not).
Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de>
