Subject: drm/vboxvideo: Initialize data needed to map fbdev memory
|
|
Patch-mainline: Not yet
|
|
Git-commit: 4153ec3d267288659638e2397bcae5298e7f5930
|
|
References: boo#977200

|
|
|
Due to a missing initialization there was no way to map fbdev memory.
|
|
Thus for example using the Xserver with the fbdev driver failed.
|
|
This fix adds initialization for fix.smem_start and fix.smem_len
|
|
in the fb_info structure, which fixes this problem.
