Armada38x wants to modify its rtc_class_ops to remove the interrupt handling when there is no usable interrupt, but this means we leave function pointers in writable memory. Since rtc_class_ops is small, arrange to have two instances, one for when we have interrupts, and one for when we have none, both marked const. This allows the compiler to place them in read-only memory, which is better than placing them in __ro_after_init. Thanks to Bhumika Goyal <bhumirks@gmail.com> for pointing out that the structure was writable and submitting a patch to add __ro_after_init.

README
Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
