The struct hfi_session_get_property_pkt is always used to fetch a
single property. Make that explicit in the code and avoid a single
element array at the end of the struct.
This change fixes the following cocci warning:
drivers/media/platform/qcom/venus/hfi_cmds.h:194:5-9: WARNING use flexible-array member instead (https://www.kernel.org/doc/html/latest/process/deprecated.html#zero-length-and-one-element-arrays)

This field is never used, but if we remove it we would change the size
of the struct and can lead to behavior change. Stay on the safe side by
replacing the single element array with a single element field.

in venus_probe, core->work is bound with venus_sys_error_handler, which is
used to handle error. The code use core->sys_err_done to make sync work.
The core->work is started in venus_event_notify.
If we call venus_remove, there might be an unfished work. The possible
sequence is as follows:
CPU0 CPU1
|venus_sys_error_handler
venus_remove |
hfi_destroy |
venus_hfi_destroy |
kfree(hdev); |
|hfi_reinit
|venus_hfi_queues_reinit

Fix it by canceling the work in venus_remove.

Vicodec will ignore en/decoder commands if the CAPTURE queue is not
streaming. But this prevents CMD_STOP from being used during a dynamic
resolution change to mark the last source buffer. Since CMD_STOP is
ignored, but doesn’t fail, there is no warning that the command needs to
be resent, and CAPTURE will continue to attempt to dequeue buffers
waiting, futilely, for one with V4L2_BUF_FLAG_LAST.
Fix this problem by carrying out en/decoder commands even if CAPTURE is
not streaming.

The driver has an OF match table, still, it uses an ID lookup table for
retrieving match data. Currently, the driver is working on the
assumption that an I2C device registered via OF will always match a
legacy I2C device ID. The correct approach is to have an OF device ID
table using i2c_get_match_data() if the devices are registered via OF/ID.
Unify the OF/ID table by using MEDIA_BUS_FMT as match data for both these
tables and replace the ID lookup table for the match data by
i2c_get_match_data() and simplifly probe() and mt9p031_init_state().
While at it, remove the trailing comma in the terminator entry for the OF
table making code robust against (theoretical) misrebases or other similar
things where the new entry goes _after_ the termination without the
compiler noticing.

The BLS parameters passed by userspace are specified for named colour
channels (R, Gr, Gb and B), while the hardware registers reference
positions in the 2x2 CFA pattern (A, B, C and D).
The BLS values are swapped based on the CFA pattern when writing to or
reading from registers, using hand-roled switch statements. The logic is
duplicated already, and new code will require similar processing. Move
the swap logic to a shared function, using static data to control the

For any changes of struct fd representation we need to
turn existing accesses to fields into calls of wrappers.
Accesses to struct fd::flags are very few (3 in linux/file.h,
1 in net/socket.c, 3 in fs/overlayfs/file.c and 3 more in
explicit initializers).
Those can be dealt with in the commit converting to
new layout; accesses to struct fd::file are too many for that.
This commit converts (almost) all of f.file to
fd_file(f). It's not entirely mechanical ('file' is used as
a member name more than just in struct fd) and it does not
even attempt to distinguish the uses in pointer context from
those in boolean context; the latter will be eventually turned
into a separate helper (fd_empty()).
NOTE: mass conversion to fd_empty(), tempting as it
might be, is a bad idea; better do that piecewise in commit
that convert from fdget...() to CLASS(...).

assumed when allocating memory for the scratch buffers and when
initializing the vb2 queue.
In order to prepare to support the "extensible" format beside the
existing "fixed" one, add support in the driver for both formats by
caching a pointer to the active one in the driver structure and use it
in the vb2 queue operations and subdev pad operations implementations.
Do not yet allow userspace to select between the two formats as the
support for the "extensible" format parsing will be introduced in a later
patch in the series.
While at it, document the un-documented ycbcr_encoding field of
struct rkisp1_params_ops.

The ISP parameters buffers are queued by userspace to the params video
device and appended by the driver to the list of available buffers for
later consumption.
As the parameters buffer is mapped in the userspace process memory,
applications have access to the buffer content after the buffer has
been queued.
To prevent userspace from modifying the contents of the parameters buffer
after it has been queued to the video device, add to 'struct
rkisp1_params_buffer' a scratch buffer where to copy the parameters.
Allocate the scratch buffer in the vb2 buf_init() operation and copy the
buffer content in the buf_prepare() operation. Free the scratch
buffer in the newly introduced buf_cleanup() operation handler.
Modify the ISP configuration function to access the ISP configuration
from the cached copy of the parameters buffer instead of using the
userspace-mapped one.

Create the 'struct rkisp1_params_buffer' type that wraps a
vb2_v4l2_buffer to prepare to hold a copy of the parameters buffer that
will be used to cache the user-provided configuration buffer in the
following patches.
Replace usage of 'struct rkisp1_buffer' with 'struct
rkisp1_params_buffer' in rkisp1-params.c to prepare for that.

The rkisp1 driver stores ISP configuration parameters in the fixed
rkisp1_params_cfg structure. As the members of the structure are part of
the userspace API, the structure layout is immutable and cannot be
extended further. Introducing new parameters or modifying the existing
ones would change the buffer layout and cause breakages in existing
applications.
The allow for future extensions to the ISP parameters, introduce a new
extensible parameters format, with a new format 4CC. Document usage of
the new format in the rkisp1 admin guide.

There is a confusing pattern in the kernel to use a variable named
'timeout' to store the result of wait_event_timeout() causing
patterns like:
timeout = wait_event_timeout(...)
if (!timeout) return -ETIMEDOUT;
with all kinds of permutations. Use 'time_left' as a variable to make the
code self explaining.
