2c0c19b681 fbdev: fbmem: Fix double free of 'fb_info->pixmap.addr' 
savagefb and some other drivers call kfree to free 'info->pixmap.addr'
even after calling unregister_framebuffer, which may cause double free.

Fix this by setting 'fb_info->pixmap.addr' to NULL after kfree in
unregister_framebuffer.

The following log reveals it:

f474bb3000 dt-bindings: display: simple: Add Vivax TPC-9150 panel 
This tablet display is unique and hence must be added to documentation.
Unfortunately, it's real make and number is not known due to obscure and
missing documentation and lack of writing on the display assembly
itself.

So the natural alternative that came to mind is to name the panel after
the device that contained it (an Android tablet). Hopefully that isn't
an issue.

I can confirm that the parameters that I've obtained are correct since
they came from a dump of the original Android OS.

1518496578 drm/bridge/lontium-lt9611uxc: fix provided connector suport 
- set DRM_CONNECTOR_POLL_HPD as the connector will generate hotplug
  events on its own

- do not call drm_kms_helper_hotplug_event() unless mode_config.funcs
  pointer is not NULL to remove possible kernel oops.

9962601ca5 drm/bridge: dw-hdmi-cec: Make use of the helper function devm_add_action_or_reset() 
The helper function devm_add_action_or_reset() will internally
call devm_add_action(), and if devm_add_action() fails then it will
execute the action mentioned and return the error code. So
use devm_add_action_or_reset() instead of devm_add_action()
to simplify the error handling, reduce the code.

c921ff373b dma-buf: add dma_resv_for_each_fence_unlocked v8 
Abstract the complexity of iterating over all the fences
in a dma_resv object.

The new loop handles the whole RCU and retry dance and
returns only fences where we can be sure we grabbed the
right one.

v2: fix accessing the shared fences while they might be freed,
    improve kerneldoc, rename _cursor to _iter, add
    dma_resv_iter_is_exclusive, add dma_resv_iter_begin/end

v3: restructor the code, move rcu_read_lock()/unlock() into the
    iterator, add dma_resv_iter_is_restarted()

v4: fix NULL deref when no explicit fence exists, drop superflous
    rcu_read_lock()/unlock() calls.

v5: fix typos in the documentation

v6: fix coding error when excl fence is NULL

v7: one more logic fix

v8: fix index check in dma_resv_iter_is_exclusive()

e7bd95a7ed drm/edid: Fix crash with zero/invalid EDID 
In the commit bac9c29482 ("drm/edid: Break out reading block 0 of
the EDID") I broke out reading the base block of the EDID to its own
function. Unfortunately, when I did that I messed up the handling when
drm_edid_is_zero() indicated that we had an EDID that was all 0x00 or
when we went through 4 loops and didn't get a valid EDID. Specifically
I needed to pass the broken EDID to connector_bad_edid() but now I was
passing an error-pointer.

Let's re-jigger things so we can pass the bad EDID in properly.
