[25/90] drm/i915: Fix typo in DRM_I915_OVERLAY_PUT_IMAGE ioctl define

From: Greg KH

3.0-stable review patch. If anyone has any objections, please let us know.


From: Ole Henrik Jahren <olehenja@xxxxxxxxxxxxxx>

commit 842d452985300f4ec14c68cb86046e8a1a3b7251 upstream.

Because of a typo, calling ioctl with DRM_IOCTL_I915_OVERLAY_PUT_IMAGE
is broken if the macro is used directly. When using libdrm the bug is
not hit, since libdrm handles the ioctl encoding internally.

The typo also leads to the .cmd and .cmd_drv fields of the drm_ioctl
structure for DRM_I915_OVERLAY_PUT_IMAGE having inconsistent content.
