[PATCH] fbdev: geocode: Add the missed pci_disable_device() for gx1fb_map_video_memory()
From: Chuhong Yuan <hidden>
Date: 2020-06-03 09:25:59
Although gx1fb_probe() has handled the failure of gx1fb_map_video_memory()
partly, it does not call pci_disable_device() as gx1fb_map_video_memory()
calls pci_enable_device().
Add the missed function call to fix the bug.
