Currently, the `port >= N_CSI_PORTS || err` checks for ISP2400 are always evaluated as true because the err variable is set to `-EINVAL` on declaration but the variable is never used until the evaluation. Looking at the diff of commit3c0538fbad("media: atomisp: get rid of most checks for ISP2401 version"), the `port >= N_CSI_PORTS` check is for ISP2400 and the err variable check is for ISP2401. Fix this issue by adding ISP version test there accordingly.

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.
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.
