The mc5602_brigde.h is included at m5602 submodules. This

In this specific case, this is somewhat intentional, as those
values are actually used in parts of the driver. The code assumes
that gcc optimizer it and not actually create any var, but convert
it to immediate access at the routines.
Yet, as we want to shut up gcc warnings, let's use #define, with
is the standard way to store values that will use assembler's
immediate access code.

The vsp1_du_atomic_update_ext() function takes 7 RPF configuration
parameters, and more will likely be added later. This makes the code
difficult to read and error-prone as multiple parameters have the same
type.
Make the API safer and easier to extend in the future by grouping all
parameters in a structure. Use macro magic to ease the transition to the
new function by allowing the old and new functions to be called using
the same name. The macros and static inline wrapper will be removed as
soon as the caller is updated.

When a buffer is being dequeued using VIDIOC_DQBUF IOCTL, the exact buffer
which will be dequeued is not known until the buffer has been removed from
the queue. The number of planes is specific to a buffer, not to the queue.
This does lead to the situation where multi-plane buffers may be requested
and queued with n planes, but VIDIOC_DQBUF IOCTL may be passed an argument
struct with fewer planes.
__fill_v4l2_buffer() however uses the number of planes from the dequeued
videobuf2 buffer, overwriting kernel memory (the m.planes array allocated
in video_usercopy() in v4l2-ioctl.c) if the user provided fewer
planes than the dequeued buffer had. Oops!

When driver unbinds while media_ioctl is in progress, cdev_put() fails with
when app exits after driver unbinds.
Add devnode struct device kobj as the cdev parent kobject. cdev_add() gets
a reference to it and releases it in cdev_del() ensuring that the devnode
is not deallocated as long as the application has the device file open.
media_devnode_register() initializes the struct device kobj before calling
cdev_add(). media_devnode_unregister() does cdev_del() and then deletes the
device. devnode is released when the last reference to the struct device is
gone.
This problem is found on uvcvideo, em28xx, and au0828 drivers and fix has
been tested on all three.

struct media_devnode is currently embedded at struct media_device.
While this works fine during normal usage, it leads to a race
condition during devnode unregister. the problem is that drivers
assume that, after calling media_device_unregister(), the struct
that contains media_device can be freed. This is not true, as it
can't be freed until userspace closes all opened /dev/media devnodes.
In other words, if the media devnode is still open, and media_device
gets freed, any call to an ioctl will make the core to try to access
struct media_device, with will cause an use-after-free and even GPF.
Fix this by dynamically allocating the struct media_devnode and only
freeing it when it is safe.

Along all media controller code, "mdev" is used to represent
a pointer to struct media_device, and "devnode" for a pointer
to struct media_devnode.
However, inside media-devnode.[ch], "mdev" is used to represent
a pointer to struct media_devnode.
This is very confusing and may lead to development errors.
So, let's change all occurrences at media-devnode.[ch] to
also use "devnode" for such pointers.
This patch doesn't make any functional changes.
