From 8ca1a765ee066b9f04f39c69d8f3678c06557257 Mon Sep 17 00:00:00 2001 From: Terje Bergstrom Date: Wed, 24 Jan 2018 13:06:37 -0800 Subject: gpu: nvgpu: Remove NVGPU_IOCTL_GET_BUFFER_INFO The IOCTL was introduced for making efficient query of buffer identity and size. It was never taken into use, and it adds a dependency to Tegra specific dma_buf API, so remove it.
