Commit 6c87e5c3ec ("drm: Rename drm_connector_unplug_all() to
drm_connector_unregister_all()") replaced a manual connectors list walk
in drm_connector_unregister_all() with drm_for_each_connector(). The
list was walked without the mode config mutex locked as that ends up in
a clash with sysfs, but drm_connector_unregister_all() warns when the
mutex isn't locked.
The problem is known and doesn't require a large warning every time
drm_connector_unregister_all() is called. Fix it by reverting to manual
list walk.

Some hubs are forgetful, and end up forgetting whatever GUID we set
previously after we do a suspend/resume cycle. This can lead to
hotplugging breaking (along with probably other things) since the hub
will start sending connection notifications with the wrong GUID. As
such, we need to check on resume whether or not the GUID the hub is
giving us is valid.

When userspace closes a handle, we remove it from the file->object_idr
and then tell the driver to drop its references to that file/handle.
However, as the file/handle is already available again for reuse, it may
be reallocated back to userspace and active on a new object before the
driver has had a chance to drop the old file/handle references.
Whilst calling back into the driver, we have to drop the
file->table_lock spinlock and so to prevent reusing the closed handle we
mark that handle as stale in the idr, perform the callback and then
remove the handle. We set the stale handle to point to the NULL object,
then any idr_find() whilst the driver is removing the handle will return
NULL, just as if the handle is already removed from idr.
Note: This will be used to have a direct handle -> vma lookup table,
instead of first a handle -> obj lookup, and then an (obj, vm) -> vma
lookup.
v2: Use NULL rather than an ERR_PTR to avoid having to adjust callers.
idr_alloc() tracks existing handles using an internal bitmap, so we are
free to use the NULL object as our stale identifier.
v3: Needed to update the return value check after changing from using
the stale error pointer to NULL.

It may caused a dead lock if we flush the hpd work in bridge disable time.
The normal flow would like:
IN --> DRM IOCTL
1. Acquire crtc_ww_class_mutex (DRM IOCTL)
IN --> analogix_dp_bridge
2. Acquire hpd work lock (Flush hpd work)
3. HPD work already in idle, no need to run the work function.
OUT <-- analogix_dp_bridge
OUT <-- DRM IOCTL
The dead lock flow would like:
IN --> DRM IOCTL
1. Acquire crtc_ww_class_mutex (DRM IOCTL)
IN --> analogix_dp_bridge
2. Acquire hpd work lock (Flush hpd work)
IN --> analogix_dp_hotplug
IN --> drm_helper_hpd_irq_event
3. Acquire mode_config lock (This lock already have been acquired in previous step 1)
** Dead Lock Now **
It's wrong to flush the hpd work in bridge->disable time, I guess the
original code just want to ensure the delay work must be finish before
encoder disabled.
The flush work in bridge disable time is try to ensure the HPD event
won't be missed before display card disabled, actually we can take a
fast respond way(interrupt thread) to update DRM HPD event to fix the
delay update and possible dead lock.

Split the dp core driver from exynos directory to bridge directory,
and rename the core driver to analogix_dp_*, rename the platform
code to exynos_dp.
Beside the new analogix_dp driver would export six hooks.
"analogix_dp_bind()" and "analogix_dp_unbind()"
"analogix_dp_suspned()" and "analogix_dp_resume()"
"analogix_dp_detect()" and "analogix_dp_get_modes()"
The bind/unbind symbols is used for analogix platform driver to connect
with analogix_dp core driver. And the detect/get_modes is used for analogix
platform driver to init the connector.
They reason why connector need register in helper driver is rockchip drm
haven't implement the atomic API, but Exynos drm have implement it, so
there would need two different connector helper functions, that's why we
leave the connector register in helper driver.

iser-target to use the common caller now available to RDMA kernel
consumers in v4.6+ code"

Commit d4edcf0d56 ("mm/gup: Switch all callers of get_user_pages() to
not pass tsk/mm") switched get_user_pages() callers to the simpler model
where they no longer pass in the thread and mm pointer. But since then
we've merged changes to a few drivers that re-introduce use of the old
interface. Let's fix them up.
They continued to work fine (thanks to the truly disgusting macros
introduced in commit cde70140fe: "mm/gup: Overload get_user_pages()
functions"), but cause unnecessary build noise.
