The `insn_read` handler for the calibration subdevice (`ni_calib_insn_read()`) currently ignores `insn->n` (the number of samples to read) and assumes a single sample is to be read into `data[0]`. Fortunately, the Comedi core ensures that `data[]` has a length of at least 16, so there is no problem with array bounds. The usual Comedi convention for `insn_read` handlers is to read the same channel `insn->n` times into successive elements of `data[]`, so let's do that. Also, follow the usual Comedi convention and return `insn->n` from the handler to indicate success (although any non-negative value will do).

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.
