The `insn_read` handler for the EEPROM subdevice (`apci3501_eeprom_insn_read()`) currently ignores `insn->n` (the number of samples to be read) and assumes a single sample is to be read. But `insn->n` could be 0, meaning no samples should be read, in which case `data[0]` ought not to be written. (The comedi core at least ensures that `data[0]` exists, but we should not rely on that.) Following the usual Comedi guidelines and interpret `insn->n` as the number of samples to be read, but only read the EEPROM location once and make `insn->n` copies, as we don't expect the contents of the EEPROM location to change between readings.

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.
