From DT point of view, in general, drivers should be asking for a
specific port number because their function is fixed in the binding.
of_graph_get_next_endpoint() doesn't match to this concept.
Simply replace
- of_graph_get_next_endpoint(xxx, NULL);
+ of_graph_get_endpoint_by_regs(xxx, 0, -1);

Change the interface of power management functions in s5p_mfc_pm.c to
accept the pointer to S5P MFC device structure. instead of relying on
file-scope static variable. This makes code easier to read and modify
in case more devices are added.

Context bit is set for hardware execution if there is a buffer in
source and destination queue before calling try_run in the
init_buffers function. Now there will be a new context created and
hardware will be invoked for the buffer queued instead of waiting for
another buffer to be queued from userspace to set this context bit for
hw execution.

Switch all drivers accessing sub-device state to use the stream-aware
functions. We will soon remove the old ones.

Additionally drivers/media/i2c/s5k5baf.c and
drivers/media/platform/samsung/s3c-camif/camif-capture.c have been
manually changed as Coccinelle didn't. Further local variables have been
removed as they became unused as a result of the other changes.
Also Coccinelle introduced indentation by space in files
drivers/media/i2c/st-mipid02.c and
drivers/media/platform/rockchip/rkisp1/rkisp1-isp.c. This has been also
corrected.

This I2C bus is used by the firmware only and it seems I2C_CLASS_SPD
device auto-detection has never been used. So we can safely remove it.
That's one further step towards removing I2C_CLASS_SPD completely.

As &dev->condlock is acquired under irq context along the following
call chain from s5p_mfc_irq(), other acquisition of the same lock
inside process context or softirq context should disable irq avoid double
lock. enc_post_frame_start() seems to be one such function that execute
under process context or softirq context.
<deadlock #1>
enc_post_frame_start()
--> clear_work_bit()
--> spin_loc(&dev->condlock)
<interrupt>
--> s5p_mfc_irq()
--> s5p_mfc_handle_frame()
--> clear_work_bit()
--> spin_lock(&dev->condlock)
This flaw was found by an experimental static analysis tool I am
developing for irq-related deadlock.
To prevent the potential deadlock, the patch change clear_work_bit()
inside enc_post_frame_start() to clear_work_bit_irqsave().

s3c_camif_register_video_node() works with video_device structure stored
as a field of camif_vp, so it should not be kfreed.
But there is video_device_release() on error path that do it.
Found by Linux Verification Center (linuxtesting.org) with SVACE.

Devicetree for the FIMC IS camera included duplicated PMU node as its
child like:
soc@0 {
system-controller@10020000 { ... }; // Real PMU
camera@11800000 {
fimc-is@12000000 {
// FIMC IS camera node
pmu@10020000 {
reg = <0x10020000 0x3000>; // Fake PMU node
};
};
};
};
This is not a correct representation of the hardware. Mapping the PMU
(Power Management Unit) IO memory should be via syscon-like phandle
(samsung,pmu-syscon, already used for other drivers), not by duplicating
"pmu" Devicetree node inside the FIMC IS. Backward compatibility is
preserved.

There is no need to call the dev_err() function directly to print a custom
message when handling an error from platform_get_irq() function as
it is going to display an appropriate error message in case of a failure.

Set the v4l2_device already in async notifier init, so struct device
related to it will be available before the notifier is registered. This
requires separating notifier initialisation into two functions, one that
takes v4l2_device as its argument, v4l2_async_nf_init and
v4l2_async_subdev_nf_init, for sub-device notifiers. Registering the
notifier will use a single function, v4l2_async_nf_register.
This is done in order to make struct device available earlier, during
construction of the async connections, for sensible debug prints.

Rename v4l2_async_subdev as v4l2_async_connection, in order to
differentiate between the sub-devices and their connections: one
sub-device can have many connections but the V4L2 async framework has so
far allowed just a single one. Connections in this context will later
translate into either MC ancillary or data links.
This patch prepares changing that relation by changing existing users of
v4l2_async_subdev to switch to v4l2_async_connection. Async sub-devices
themselves will not be needed anymore
Additionally, __v4l2_async_nf_add_subdev() has been renamed
__v4l2_async_nf_add_connection().
