Subject: [PATCH v5 1/3] VT: Use macros to define ioctls
Date: Wed, 17 Apr 2024 19:37:35 +0200
Message-ID: <e4229fe2933a003341e338b558ab1ea8b63a51f6.1713375378.git.legion@kernel.org>

All other headers use _IOC() macros to describe ioctls for a long time
now. This header is stuck in the last century.

Simply use the _IO() macro. No other changes.
