e9be771344'struct spmi_voltage_range' are only modified at runtime to compile a field, n_voltages, that could be computed at compile time. So, simplify spmi_calculate_num_voltages() and compute n_voltages at compile time within the SPMI_VOLTAGE_RANGE macro. Constifying these structures moves some data to a read-only section, so increase overall security.

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.
