The configure_channels() function has a double free because
configure_memdma_and_inputblock() calls free_input_block() and then
it's called again in the error handling code.

Pointer common is being assigned a value in a for-loop and the pointer
is never read afterwards. The assignment is redundant and can be removed.

While testing Rockchip RK3399 with both ISPs enabled, a dmesg error
was observed:
```
[ 15.559141] debugfs: Directory 'rkisp1' with parent '/' already present!
```
Fix it by using the device name for the debugfs subdirectory name
instead of the driver name, thus preventing name collision.

The only usage of the v4l2_m2m_ops structs is to pass their address to

There is no need to hold the group lock when unregistering the notifier,
but doing so triggers a warning about a possible cyclic lock dependency.
The lock warning cover the case where a subdevice is about to be bound
to the notifier at the same time as it's unregistered. The locking for
this scenario is handled in the v4l2-async framework so it's safe to
remove the lock in the driver. This match the locking logic in the
driver for when the notifier in question is registered.

The VIN driver have an internal concept of capture groups that covers
multiple instances of the driver. This is handled using the shared media
graph and a single notifier shared between all VIN instances.
This design do not work well if an individual VIN where to be unbound on
its own. The design could be improved up on to allow for this but would
require large changes in the v4l2-async framework. To avoid the
situation suppress the bind and unbind nodes in sysfs.

The v4l2-async framework's subdev notifiers do not behave correctly if a
device in the middle of the pipeline is unbound and then rebound. The
v4l2-subdevices upstream from the device being rebound gets confused as
they receive no notification of the device unbound and can't cleanup
their state and when they are rebound to the new v4l2-subdev notifier
they try to reinitialize their internal state, this may include things
as trying to create links that already exists and in some cases crash
the system, for example the adv748x.
This should be solved in the v4l2-async framework, but as a stop-gap
measure suppress the bind and unbind sysfs nodes for the rcar-csi2
driver so it can't be used to crash the system.

This change fixes two issues with the size constraints for buffers.
- There is no width alignment constraint for RGB formats. Prior to this
change they were treated as YUV and as a result were more restricted
than needed. Add a new check to differentiate between the two.
- The minimum width and height supported is 5x2, not 2x4, this is an
artifact from the driver's soc-camera days. Fix this incorrect
assumption.

Before reading which slot was captured to by examining the module status
(VnMS) register, make sure something was captured at all by examining
the interrupt status register (VnINTS).
Failing this a buffer maybe completed before it was captured too.

concurrent video sessions
In existing implementation, core_clk_setrate() is getting called
concurrently in concurrent video sessions. Before the previous call to
core_clk_setrate returns, new call to core_clk_setrate is invoked from
another video session running concurrently. This results in latest
calculated frequency being set (higher/lower) instead of actual frequency
required for that video session. It also results in stability crashes
mention below. These resources are specific to video core, hence keeping
under core lock would ensure that they are estimated for all running video
sessions and called once for the video core.

The mtk-vcodec uses some internal defined debug formats for
printing. This patch fixes some things in those defines:
1. use the 'pr_fmt' define to print function name and line.
2. remove 'if(DEBUG)' condition for the defines. This condition
prevents the debugs from being shown in case of dynamic debugs.
Instead replace 'pr_info' with 'pr_debug'
3. remove module parameters that enable/disable debug.
There is no reason for the driver to have those params. Having
those params require the user to explicitly set them when user
wants to see debug prints instead of using the global debugs
setting as expected by drivers to conform.
In addition to that, fix some warnings about debug formatting

camif_unregister_media_entities
In the error handling of s3c_camif_probe, s3c_camif_unregister_subdev
may be executed twice, one is from camif_unregister_media_entities.
Although there is sanity check about the registration status,
it is not good to call s3c_camif_unregister_subdev twice in the error
handling code.
Fix this by moving s3c_camif_unregister_subdev out of
camif_unregister_media_entities, and add a s3c_camif_unregister_subdev
in the s3c_camif_remove.

hsfreqrange should be chosen based on the calculated mbps which
is closer to the default bit rate and within the range as per
table[1]. But current calculation always selects first value which
is greater than or equal to the calculated mbps which may lead
to chosing a wrong range in some cases.
For example for 360 mbps for H3/M3N
Existing logic selects
Calculated value 360Mbps : Default 400Mbps Range [368.125 -433.125 mbps]
This hsfreqrange is out of range.
The logic is changed to get the default value which is closest to the
calculated value [1]
Calculated value 360Mbps : Default 350Mbps Range [320.625 -380.625 mpbs]
[1] specs r19uh0105ej0200-r-car-3rd-generation.pdf [Table 25.9]
Please note that According to Renesas in Table 25.9 the range for
220 default value is corrected as below
|Range (Mbps) | Default Bit rate (Mbps) |
-----------------------------------------------
| 197.125-244.125 | 220 |

The driver already has logic to detect if it fails to stop properly and
report this error to the user. The driver however did not report the
unused buffers or buffers given to the hardware (if any) with an error,
the buffers where instead returned to user-space in the active state.
Build on the existing detection of the error condition and correctly
return the buffers with an error if it triggers.

If res-chg, VE_INTERRUPT_MODE_DETECT_WD irq will be raised. But
v4l2_input_status won't be updated to no-signal immediately until
aspeed_video_get_resolution() in aspeed_video_resolution_work().
During the period of time, aspeed_video_start_frame() could be called
because it doesn't know signal becomes unstable now. If it goes with
aspeed_video_init_regs() of aspeed_video_irq_res_change()
simultaneously, it will mess up hw state.
