commit 70f1ae5f0e7f44edf842444044615da7b59838c1 upstream.
Read/write callbacks registered with nvmem core expect 0 to be returned
on success and a negative value to be returned on failure.
isl1208_nvmem_read()/isl1208_nvmem_write() currently return the number of
bytes read/written on success, fix to return 0 on success and negative on
failure.
Fixes: c3544f6f51ed ("rtc: isl1208: Add new style nvmem support to driver")

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.
