Call on v4l2_get_active_data_lanes() to check if the driver reports that the number of lanes actively used by the MIPI CSI transmitter differs to the maximum defined in device tree. If the number of active data lanes reported by the driver is invalid, catch and return the error. If the operation is not supported, fall back to the number of allowed data lanes.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
