From 9c7d3d3e289c9870ae688780a0f9807bb5ae9faf Mon Sep 17 00:00:00 2001 From: =?utf8?q?Ville=20Syrj=C3=A4l=C3=A4?= Date: Fri, 27 Mar 2015 15:51:55 +0200 Subject: [PATCH] drm: Fix DRM_IOCTL_DEF_DRV() MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Currently DRM_IOCTL_DEF_DRV does '[DRM_IOCTL_NR(DRM_##ioctl)]' which doesn't make much sense since DRM_##ioctl is already a the raw ioctl number. So change it to 'DRM_IOCTL_NR(DRM_IOCTL_##ioctl) - DRM_COMMAND_BASE' which means the DRM_IOCTL_NR() now makes sense, and also this also means if there's a mistake in the DRM_IOCTL_##ioctl macros we might get a warning about it (eg. we would have gotten a sparse warning about the i915 colorkey get/set ioctl being defined to be the same thing).
