The of_node member in struct drm_bridge is hidden when CONFIG_OF
is disabled, causing a build error:
drivers/gpu/drm/bridge/dw-hdmi.c: In function '__dw_hdmi_probe':
drivers/gpu/drm/bridge/dw-hdmi.c:2063:14: error: 'struct drm_bridge' has no member named 'of_node'
We could fix this either using a Kconfig dependency on CONFIG_OF
or making the one line conditional. The latter gives us better
compile test coverage, so this is what I'm doing here.

"A single lockdep fix, nothing else going on. This makes lockdep
noiseless and work properly with threaded GPIO IRQchips.
Summary:
Fix a lockdep issue: the threaded irqchips also need their unique key,
and take this opportunity to get rid of the horrible macro and replace
it with a static inline"

"drm fixes across the board.
Okay holidays and LCA kinda caught up with me, I thought I'd get some
of this dequeued last week, but Hobart was sunny and warm and not all
gloomy and rainy as usual.
This is a bit large, but not too much considering it's two weeks stuff
from AMD and Intel.
core:
- one locking fix that helps with dynamic suspend/resume races
i915:
- mostly GVT updates, GVT was a recent introduction so fixes for it
shouldn't cause any notable side effects.
amdgpu:
- a bunch of fixes for GPUs with a different memory controller design
that need different firmware.
exynos:
- decon regression fixes
msm:
- two regression fixes
etnaviv:
- a workaround for an mmu bug that needs a lot more work.
virtio:
- sparse fix, and a maintainers update"

The ucounts_lock is being used to protect various ucounts lifecycle
management functionalities. However, those services can also be invoked
when a pidns is being freed in an RCU callback (e.g. softirq context).
This can lead to deadlocks. There were already efforts trying to
prevent similar deadlocks in add7c65ca426 ("pid: fix lockdep deadlock
warning due to ucount_lock"), however they just moved the context
from hardirq to softrq. Fix this issue once and for all by explictly
making the lock disable irqs altogether.

This means we shouldn't swap the width and height ourselves when a

Remove the check enforcing that src_w and src_h match crtc_w and crtc_h,
as this prevents rotation from working.
The check was intended to disallow scaling, but
drm_plane_helper_check_state() does that for us, while also taking
rotation into account, so the removed check was redundant in any case.

The allocation for the bitmap may become very large, larger than
MAX_ORDER, for large requests. We fail gracefully by falling back to

On Ideapad laptops, ACPI event 1 is currently not handled. Many models
log "ideapad_laptop: Unknown event: 1" every 20 seconds or so while
running on battery power. Some convertible laptops receive this event
when switching in and out of tablet mode.
This adds and additional case for event 1 in ideapad_acpi_notify to call
ideapad_input_report(priv, vpc_bit), so that the event is reported to
userspace and we avoid unnecessary logging.

Pull libnvdimm fixes from Dan Williams:
"Two fixes:
- a regression fix for the multiple-pmem-namespace-per-region support
added in 4.9. Even if an existing environment is not using that
feature the act of creating and a destroying a single namespace
with the ndctl utility will lead to the proliferation of extra
unwanted namespace devices.
- a fix for the error code returned from the pmem driver when the
memcpy_mcsafe() routine returns -EFAULT. Btrfs seems to be the only
block I/O consumer that tries to parse the meaning of the error
code when it is non-zero.
Neither of these fixes are critical, the namespace leak is awkward in
that it can cause device naming to change and complicates debugging
namespace initialization issues. The error code fix is included out of
caution for what other consumers might be expecting -EIO for block I/O
errors"

It is useful to have this trace as it pairs nicely with the vma_unbind

Added inside the i915_vma_bind function (was outside before) to keep a
similar placement as trace_i915_vma_unbind.
