The comment in the probe function stating that it disables oscillator stop detection and glitch filtering is incorrect as it sets bits 3 and 4 while it should be setting 5 and 6 to achieve that. Then, it is safe to assume that the oscillator failure detection is actually enabled. Properly handle oscillator failures by returning -EINVAL when the time and date are know to be incorrect and reset the flag when the time is set.

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.
