| Subject: drm/gma500: Add compat ioctl |
| |
| From: Patrik Jakobsson <patrik.r.jakobsson@gmail.com> |
| |
| commit 0a97c81a9717431e6c57ea845b59c3c345edce67 upstream. |
| |
| Hook up drm_compat_ioctl to support 32-bit userspace on 64-bit kernels. |
| It turns out that N2600 and N2800 comes with 64-bit enabled. We |
| previously assumed there where no such systems out there. |
