From 644adc3d0ff05f49fae9a7549e27dfd7e9a5afe5 Mon Sep 17 00:00:00 2001 From: Thomas Zimmermann Date: Sun, 16 May 2021 21:51:35 +0200 Subject: drm: Mark IRQ_BUSID ioctl as legacy The functionality is only implemented for legacy drivers. Mark the ioctl as legacy and move the code behind CONFIG_DRM_LEGACY. If legacy drivers are disabled, the ioctl call now returns -EINVAL instead of -EOPNOTSUPP.
