Data about the implemented readout modes is partially stored in imx274_formats[], the rest is scattered in several arrays. The latter are then accessed using the mode index, e.g.: min_frame_len[priv->mode_index] Consolidate all these data in imx274_formats[], and store a pointer to the selected mode (i.e. imx274_formats[priv->mode_index]) in the main device struct. This way code to use these data becomes more readable, e.g.: priv->mode->min_frame_len This removes lots of scaffolding code and keeps data about each mode in a unique place. Also remove a parameter to imx274_mode_regs() that is now unused. While this adds the mode pointer to the device struct, it does not remove the mode_index from it because mode_index is still used in two dev_dbg() calls. This will be handled in a follow-up commit.

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 Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
