The ad7124_init_config_vref() function writes the AD7124_ADC_CONTROL register for each channel that is configured to use the internal reference. The ad7124_write_config()function performs 7 SPI transfers for configuring 2 registers: config_x and filter_x. Reduce the number of SPI transfers: -during the probe by only setting the st->adc_control value in ad7124_init_config_vref() and writing to the device only at the end of ad7124_setup(). -in ad7124_write_config() by grouping writes to the same register.

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.
