drm/tegra: Fix crash caused by reference count imbalance
Commit
d2307dea14a4 ("drm/atomic: use connector references (v3)") added
reference counting for DRM connectors and this caused a crash when
exercising system suspend on Tegra114 Dalmore.
The Tegra DSI driver implements a Tegra specific function,
tegra_dsi_connector_duplicate_state(), to duplicate the connector state
and destroys the state using the generic helper function,
drm_atomic_helper_connector_destroy_state(). Following commit
d2307dea14a4 ("drm/atomic: use connector references (v3)") there is
now an imbalance in the connector reference count because the Tegra
function to duplicate state does not take a reference when duplicating
the state information. However, the generic helper function to destroy
the state information assumes a reference has been taken and during
system suspend, when the connector state is destroyed, this leads to a
crash because we attempt to put the reference for an object that has
already been freed.
Fix this by calling __drm_atomic_helper_connector_duplicate_state() from
tegra_dsi_connector_duplicate_state() to ensure that we take a reference
on a connector if crtc is set. Note that this will also copy the
connector state a 2nd time, but this should be harmless.
By fixing tegra_dsi_connector_duplicate_state() to take a reference,
although a crash was no longer seen, it was then observed that after
each system suspend-resume cycle, the reference would be one greater
than before the suspend-resume cycle. Following commit
d2307dea14a4
("drm/atomic: use connector references (v3)"), it was found that we
also need to put the reference when calling the function
tegra_dsi_connector_reset() before freeing the state. Fix this by
updating tegra_dsi_connector_reset() to call the function
__drm_atomic_helper_connector_destroy_state() in order to put the
reference for the connector.

drm/fb_helper: Fix references to dev->mode_config.num_connector
During boot, MST hotplugs are generally expected (even if no physical
hotplugging occurs) and result in DRM's connector topology changing.
This means that using num_connector from the current mode configuration
can lead to the number of connectors changing under us. This can lead to
some nasty scenarios in fbcon:
- We allocate an array to the size of dev->mode_config.num_connectors.
- MST hotplug occurs, dev->mode_config.num_connectors gets incremented.
- We try to loop through each element in the array using the new value
of dev->mode_config.num_connectors, and end up going out of bounds
since dev->mode_config.num_connectors is now larger then the array we
allocated.
fb_helper->connector_count however, will always remain consistent while
we do a modeset in fb_helper.
Note: This is just polish for 4.7, Dave Airlie's drm_connector
refcounting fixed these bugs for real. But it's good enough duct-tape
for stable kernel backporting, since backporting the refcounting
changes is way too invasive.

drm/i915/fbdev: Fix num_connector references in intel_fb_initial_config()
During boot time, MST devices usually send a ton of hotplug events
irregardless of whether or not any physical hotplugs actually occurred.
Hotplugs mean connectors being created/destroyed, and the number of DRM
connectors changing under us. This isn't a problem if we use
fb_helper->connector_count since we only set it once in the code,
however if we use num_connector from struct drm_mode_config we risk it's
value changing under us. On top of that, there's even a chance that
dev->mode_config.num_connector != fb_helper->connector_count. If the
number of connectors happens to increase under us, we'll end up using
the wrong array size for memcpy and start writing beyond the actual
length of the array, occasionally resulting in kernel panics.

There will some printed issues with above info, under certain
circumstances:
If ((BIT(0) | BIT(2)) & val) is never true, break will not happen and
delay_count will be max u32 value (?), and no DRM_INFO is printed.
Also if ((BIT(0) | BIT(2)) & val) is true at the last possible

( because of earlier delay_count-- ) and DRM_INFO is erroneously
printed.
