Subject: drm/tegra: Set sgt pointer in BO pin
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=585ee0f27ef7b8db46807b960388b7e58b60766d;p=openwrt%2Fstaging%2Fblogic.git

drm/tegra: Set sgt pointer in BO pin

Fix tegra_bo_pin() to set the parameter sgt pointer. host1x job pinning
requires the sgt to determine physical memory addresses of gathers.
