The code for the legacy RTC and the RTC class based update are pretty much the same. Consolidate the common parts into one function and just invoke the actual setter functions. For RTC class based devices the update code checks whether the offset is valid for the device, which is usually not the case for the first invocation. If it's not the same it stores the correct offset and lets the caller try again. That's not much different from the previous approach where the first invocation had a pretty low probability to actually hit the allowed window.

README
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.
