OMAPDSS: Fix crash with DT boot

2013-05-23T09:54:21+00:00

When booting with DT, there's a crash when omapfb is probed. This is
caused by the fact that omapdss+DT is not yet supported, and thus
omapdss is not probed at all. On the other hand, omapfb is always
probed. When omapfb tries to use omapdss, there's a NULL pointer
dereference crash. The same error should most likely happen with omapdrm
and omap_vout also.

To fix this, add an "initialized" state to omapdss. When omapdss has
been probed, it's marked as initialized. omapfb, omapdrm and omap_vout
check this state when they are probed to see that omapdss is actually
there.

[media] Corrected Oops on omap_vout when no manager is connected

2013-03-21T21:31:51+00:00

If no manager is connected to the vout device, the omapvid_init() function
fails. No error condition is checked, and the device is started. Later on,
when irq is serviced, a NULL pointer dereference occurs.
Also, the isr routine must be registered only if no error occurs, otherwise
the isr triggers without the proper setup, and the kernel oops again.
To prevent this, the error condition is checked, and the streamon function
exits with error. Also the isr registration call is moved after the setup
procedure is completed.

[media] omap_vout: find_vma() needs ->mmap_sem held

2013-01-06T13:01:06+00:00

Walking rbtree while it's modified is a Bad Idea(tm); besides,
the result of find_vma() can be freed just as it's getting returned
to caller.  Fortunately, it's easy to fix - just take ->mmap_sem a bit
earlier (and don't bother with find_vma() at all if virtp >= PAGE_OFFSET -
in that case we don't even look at its result).

While we are at it, what prevents VIDIOC_PREPARE_BUF calling
v4l_prepare_buf() -> (e.g) vb2_ioctl_prepare_buf() -> vb2_prepare_buf() ->
__buf_prepare() -> __qbuf_userptr() -> vb2_vmalloc_get_userptr() -> find_vma(),
AFAICS without having taken ->mmap_sem anywhere in process?  The code flow
is bloody convoluted and depends on a bunch of things done by initialization,
so I certainly might've missed something...

[media] omap_vout: Drop overlay format enumeration

2012-12-19T15:11:18+00:00

Enumerating formats for output overlays doesn't make sense, as the pixel
format is defined by the display API, not the V4L2 API. Drop the
vidioc_enum_fmt_vid_overlay ioctl operation.
