From: Patrik Jakobsson Date: Tue, 1 Nov 2016 14:43:15 +0000 (+0100) Subject: drm/gma500: Add compat ioctl X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=0a97c81a9717431e6c57ea845b59c3c345edce67;p=openwrt%2Fstaging%2Fblogic.git drm/gma500: Add compat ioctl 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.
