Hi Louis, I've done an initial review of this. Please see my comments
inline.

Rewrite these as static inline functions that take an argument. Per the
kernel style guide, avoid macros that rely on local variables with a
certain name.

test_pattern is not accessed outside the ctrl ops, so there is no need
to store it here.

This gets set in seninf_s_stream and seninf_link_setup but never read
from. Can it be removed?

Only the first mux is ever used. Should this be one address rather than
an array of addresses?

This is only ever called with mux_idx = 0.

This function is unused, so remove it.

This function is only called with the same arguments for mux, hs_pol,
vs_pol, src_type_sel, and pixel_mode. Remove these arguments and
handling for unreachable code.

Also, the return value is always 0, so lets remove the return type too.

Can these be named something more meaningful than temp?

It looks like input_data_type will only ever be in the range 0-3, per
the map_fmt function, thus we will never hit the branches where
input_data_type == JPEG_FMT. Please remove the code for unreachable
cases.

This is only ever called with mux = 0.

This function is quite large (~500 lines). Can parts of it be extracted
into helper functions with descriptive names?

Here and in other places in this function, there are redundant
expressions that do a bitwise | with zero, or bitshift 0. These should
be cleaned up.

Also, is it possible to #define constants or enums for some of these
numbers, or at least document what they mean? Splitting this function
into smaller functions may help clarify what's going on as well.

This is never defined. Should this block of code be removed?

get_csi_info can return NULL, so handle that here.

It looks like this is only ever set to 1. Can we remove it from the
struct?

Again, this is only ever set to 1.

> +	csi_mipi.csi_type = (mipi_sensor_type == MIPI_CPHY)

mipi_sensor_type is only ever set to MIPI_CPHY_NCSI2, so csi_type can
only ever be CSI_2_5G. Can we remove the csi_type member from the
struct, and any unreachable code?

> +	csi_mipi.csi_info = csi_info;

It looks like this is only ever set to PAD_10BIT. Can we remove it from
the struct?

No need to set this to 0, since it gets set two lines down.

> +	input_data_type = (unsigned int)map_fmt(priv);
> +	csi_mipi.dpcm = priv->dpcm;

priv->dpcm gets set in map_fmt, and then gets assigned to csi_mipi.dcpm
here. It isn't used anywhere else. So let's remove dpcm from the _seninf
struct and pass in &csi_mipi.dpcm as an out param.

priv->mux_select never gets read from, and elsewhere the mux is
hardcoded to 0. Should this block be removed?

priv->port is used to index into priv->ep, so let's make sure it is
within the correct range.

The docs suggest that V4L2_CID_TEST_PATTERN control is used for
generating test patterns, but it looks like seninf_enable_test_pattern
is just reading and logging register values.

No need to initialize the return value.

Maybe #define a constant such as MAX_SENSORS, and use this here and
elsewhere?

Is the (irq_handler_t) cast needed here?

Should an error be returned in this case? Also, consider changing the
check above to if (!irq) and return from there to reduce nesting.

These arrays all have the same values. Is it necessary to have three

Should media_entity_cleanup and v4l2_ctrl_handler_free be called in this
