pm_runtime_get_sync() increments the runtime PM usage counter even
when it returns an error code. Thus a pairing decrement is needed on
the error handling path to keep the counter balanced.

Currently we are considering the instances which are available
in core->inst list for load calculation in min_loaded_core()
function, but this is incorrect because by the time we call
decide_core() for second instance, the third instance not
filled yet codec_freq_data pointer.
Solve this by considering the instances whose session has started.

If lirc_dev_init() fails during module initialization, rc_core_init()
returns 0 denoting success. This can cause different issues during
further operation of the module. The patch fixes the return value of
rc_core_init() on the corresponding error handling path.

In commit f3b98e3c4d2e16 ("media: vsp1: Provide support for extended

not populated.
Correctly assign the pointer to prevent the following

The functions mtk_mdp_register/unregister_component have been created to
add / remove items from the list of components.
This will eventually enable us to specify a list of components in the
device tree instead of hardcoding them into this driver.
The list is modified by a single thread at driver probe time, and will
not be traversed by another thread until the call to pm_runtime_enable
at the end of probing.

The mtk-mdp driver uses states to check if the formats have been set
on the capture and output when turning the streaming on, setting
controls or setting the selection rectangles.
Those states are reset when 0 buffers are requested like when checking
capabilities.
This patch removes all format checks and set one by default as queues in
V4L2 are expected to always have a format set.

If fw_csr_string() returns -ENOENT, then "name" is uninitialized. So
then the "strlen(model_names[i]) <= name_len" is true because strlen()
is unsigned and -ENOENT is type promoted to a very high positive value.
Then the "strncmp(name, model_names[i], name_len)" uses uninitialized
data because "name" is uninitialized.

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.

as MEDIA_ENT_F_IO_V4L implies V4L2 video node.

When that allocation fails, filp->private_data is left uninitialized

To avoid this, reorder media_request_alloc() such that
allocating the struct file happens as the last step thus
media_request_close() will no longer get called for a partially created

The IMX290 sensor can output frames with 2/4 CSI2 data lanes. This commit
adds support for 2 lane mode in addition to the 4 lane and also
configuring the data lane settings in the driver based on system
configuration.

According to https://www.kernel.org/doc/Documentation/gpio/consumer.txt,
- all of the gpiod_set_value_xxx() functions operate with the *logical*
value. So in imx290_power_on() the reset signal should be cleared
(de-asserted) with gpiod_set_value_cansleep(imx290->rst_gpio, 0), and in
imx290_power_off() the value of 1 must be used to apply/assert the reset
to the sensor. In the device tree the reset pin is described as
GPIO_ACTIVE_LOW, and gpiod_set_value_xxx() functions take this into
account,
- when devm_gpiod_get_optional() is called with GPIOD_ASIS, the GPIO is
not initialized, and the direction must be set later; using a GPIO
without setting its direction first is illegal and will result in undefined
behavior. Fix this by using GPIOD_OUT_HIGH instead of GPIOD_ASIS (this
asserts the reset signal to the sensor initially).

The macro is defined as SET_RUNTIME_PM_OPS(suspend_fn, resume_fn, idle_fn),
so imx290_power_off must be the 1st arg, and imx290_power_on the 2nd.

With the current driver 'media-ctl -p' issued right after the imx290 driver
is loaded prints:
pad0: Source
[fmt:unknown/0x0]
The format value of zero is due to the current_format field of the imx290
struct not being initialized yet.
As imx290_entity_init_cfg() calls imx290_set_fmt(), the current_mode field
is also initialized, so the line which set current_mode to a default value
in driver's probe() function is no longer needed.

The cec_adapter struct contained a waitq field that isn't used
anywhere, so drop this.
It also contained a phys_addrs array to store any reported physical
addresses. However, this was never actually used, so this field is
removed as well. The original idea was to let the core keep track of
this information, but nothing was ever done with this. Should this
be needed in the future then it is easy enough to resurrect this.

value in debiirq()
The value av7110->debi_virt is stored in DMA memory, and it is assigned
to data, and thus data[0] can be modified at any time by malicious
hardware. In this case, "if (data[0] < 2)" can be passed, but then
data[0] can be changed into a large number, which may cause buffer
overflow when the code "av7110->ci_slot[data[0]]" is used.
To fix this possible bug, data[0] is assigned to a local variable, which
replaces the use of data[0].

CONFIG_DVB_USB_CXUSB_ANALOG is a 'bool' symbol with a dependency on the
tristate CONFIG_VIDEO_V4L2, which means it can be enabled as =y even
when its dependency is =m. This leads to a link failure:
