Those seeing crashes when using the SBUS framebuffer drivers
in 2.6.23-rc1 can try out the following patch which should
fix the problem.
Thanks.
commit c962c92edcefb92611f917ab1eb515a98e5b4848
Author: David S. Miller <davem@xxxxxxxxxxxxxxxxxxxx>

[VIDEO]: Fix OOPS in all SBUS framebuffer drivers.
All of these drivers use a silly:
struct all_info {
struct fb_info info;
struct foo_par par;
};
struct all_info *all = kzalloc(sizeof(*all), GFP_KERNEL);
all->info.par = &all->par;
etc. etc. code sequence, basically replicating the provided
framebuffer_alloc()/framebuffer_release(), and doing it badly.
Not only is this massive code duplication, it also caused a
bug in that we weren't setting the fb_info->device pointer
which results in an OOPS when fb_is_primary_device() runs.
Fix all of this by using framebuffer_{alloc,release}() and
passing in "&of_device->dev" as the device pointer.
