The key objective in ad7124_disable_one() is clearing the AD7124_CHANNEL_EN_MSK bit in the channel register. However there is no advantage to keep the other bits in that register because when the channel is used next time, all fields are rewritten anyhow. So instead of using ad7124_spi_write_mask() (which is a register read plus a register write) use a simple register write clearing the complete register. Also do the same in the .disable_all() callback by using the .disable_one() callback there.

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.
