The getter method of a field works with the field type, but its setter
expects the type of the register. This leads to an asymmetry in the
From/Into implementations required for a field with a dedicated type.
For instance, a field declared as
pub struct ControlReg(u32) {
3:0 mode as u8 ?=> Mode;
...
}
currently requires the following implementations:
impl TryFrom<u8> for Mode {
...
}
impl From<Mode> for u32 {
...
}
Change this so the `From<Mode>` now needs to be implemented for `u8`,
i.e. the primitive type of the field. This is more consistent, and will
become a requirement once we start using the TryFrom/Into derive macros
to implement these automatically.

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.
