Hi Thomas,a quick drive-by comment. On Mon, Jan 23, 2023 at 11:05:59AM +0100, Thomas Zimmermann wrote:The generic fbdev emulation names variables of type struct fb_info both 'fbi' and 'info'. The latter seems to be more common in fbdev code, so name fbi accordingly. Also replace the duplicate variable in drm_fbdev_fb_destroy().

Oh indeed; will fix. This change belongs to patch 8, which streamlines the cleanup a bit.
Best regards Thomas
