drm: Nuke SET_UNIQUE ioctl
Ever since
commit 2e1868b560315a8b20d688e646c489a5ad93eeae
Author: Eric Anholt <anholt@freebsd.org>
Date: Wed Jun 16 09:25:21 2004 +0000
DRI trunk-20040613 import
the X server supports drm 1.1, thus doesn't call call libdrm's
drmSetBusid - the sole user of this ioctl. When reviewing this note
that for hilarity both the kernel-internal functions (set_busid) and
the libdrm wrapper (drmSetBusid) have names not matching this ioctl
(SET_UNIQUE).
v2: Polish commit message (Emil).
