…drm-misc into drm-next
A bunch of fixes to avoid null pointer dereference in fbcon, fix a return
in xen, some DT bindings fixes, a vc4 issue with 1920x1200 mode validation,
and a conflicting framebuffer in vboxvideo.Signed-off-by: Dave Airlie <airlied@redhat.com>

Pull ARM SoC fixes from Olof Johansson:
"We've been accruing these for a couple of weeks, so the batch is a bit
bigger than usual.Largest delta is due to a led-bl driver that is added -- there was a
miscommunication before the merge window and the driver didn't make it
in. Due to this, the platforms needing it regressed. At this point, it
seemed easier to add the new driver than unwind the changes.Besides that, there are a handful of various fixes:
- AMD tee memory leak fix
- A handful of fixlets for i.MX SCU communication
- A few maintainers woke up and realized DEBUG_FS had been missing
for a while, so a few updates of that.... and the usual collection of smaller fixes to various platforms"

The current codebase makes use of the zero-length array language
extension to the C90 standard, but the preferred mechanism to declare
variable-length types such as these ones is a flexible array member[1][2],
introduced in C99:struct foo {
int stuff;
struct boo array[];
};By making use of the mechanism above, we will get a compiler warning
in case the flexible array does not occur last in the structure, which
will help us prevent some kind of undefined behavior bugs from being
inadvertently introduced[3] to the codebase from now on.Also, notice that, dynamic memory allocations won't be affected by
this change:"Flexible array members have incomplete type, and so the sizeof operator
may not be applied. As a quirk of the original implementation of
zero-length arrays, sizeof evaluates to zero."[1]This issue was found with the help of Coccinelle.

In old days, the "host-progs" syntax was used for specifying host
programs. It was renamed to the current "hostprogs-y" in 2004.It is typically useful in scripts/Makefile because it allows Kbuild to
selectively compile host programs based on the kernel configuration.This commit renames like follows:
always -> always-y
hostprogs-y -> hostprogsSo, scripts/Makefile will look like this:
always-$(CONFIG_BUILD_BIN2C) += ...
always-$(CONFIG_KALLSYMS) += ...
...
hostprogs := $(always-y) $(always-m)I think this makes more sense because a host program is always a host
program, irrespective of the kernel configuration. We want to specify
which ones to compile by CONFIG options, so always-y will be handier.The "always", "hostprogs-y", "hostprogs-m" will be kept for backward
compatibility for a while.Signed-off-by: Masahiro Yamada

On Hyper-V, Generation 1 VMs can directly use VM's physical memory for
their framebuffers. This can improve the efficiency of framebuffer and
overall performence for VM. The physical memory assigned to framebuffer
must be contiguous. We use CMA allocator to get contiguouse physicial
memory when the framebuffer size is greater than 4MB. For size under
4MB, we use alloc_pages to achieve this.To enable framebuffer memory allocation from CMA, supply a kernel
parameter to give enough space to CMA allocator at boot time. For
example:
cma=130m
This gives 130MB memory to CAM allocator that can be allocated to
framebuffer. If this fails, we fall back to the old way of using
mmio for framebuffer.Reported-by: kbuild test robot

fb_deferred_io_work() can access the vmbus ringbuffer by calling
fbdefio->deferred_io() -> synthvid_deferred_io() -> synthvid_update().Because the vmbus ringbuffer is inaccessible between hvfb_suspend()
and hvfb_resume(), we must cancel info->deferred_work before calling
vmbus_close() and then reschedule it after we reopen the channel
in hvfb_resume().Fixes: a4ddb11d297e ("video: hyperv: hyperv_fb: Support deferred IO for Hyper-V frame buffer driver")

There is a hunk of code that is incorrectly indented, clean up the
indentation and a comment block. Also remove block braces around a

The objects in $(fb-objs) $(fb-y) $(fb-m) are linked to fb.ko .
This line adds $(fb-y) to fb-objs, so the objects from $(fb-y) are
listed twice as the dependency of the module.It works because Kbuild trims the duplicated objects from linking,
but there is no good reason to have this line.Signed-off-by: Masahiro Yamada
