In function hvfb_probe in hyperv_fb.c, it calls hvfb_getmem(hdev, info)
and return err when info->apertures is freed.
In the error1 label of hvfb_probe, info->apertures will be freed twice
by framebuffer_release(info).
My patch sets info->apertures to NULL after it was freed to avoid
double free.
Thanks for your patch.
I would like to change the prefix to "video: hyperv_fb:" to be more
specific.
