Subject: [PATCH 08/36] tty/vt: consolemap: one line = one statement
Date:   Tue,  7 Jun 2022 12:49:18 +0200
Message-Id: <20220607104946.18710-8-jslaby@suse.cz>

Some lines combine more statements on one line. This makes the code hard
to follow. Do it properly in the "one line = one statement" fashion.
