The memory pointed to by the ::rtc member is managed via devres, and no code in this driver uses it past _probe(). We can drop it from the structure and just use a local temporary variable, reducing runtime memory consumption by a few bytes. Since this now means that the structure has just one member only left, there is no need anymore to allocate data for it and pass that around via the various callbacks, just to extract that one member. Instead, we can just pass that one member and avoid the extra memory allocation for the containing struct, reducing runtime memory consumption.

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.
