From: Shawn Guo Date: Thu, 12 Jan 2017 08:27:35 +0000 (+0800) Subject: drm: zte: move struct vou_inf into zx_vou driver X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=831a8d5e0bef;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git drm: zte: move struct vou_inf into zx_vou driver Although data in struct vou_inf is defined per output device, it doesn't belong to the device itself but VOU control module. All these data can just be defined in VOU driver, and output device driver only needs to invoke VOU driver function with device ID to enable/disable specific output device.
