Voltage-controlled regulators depend on their supply regulator for retrieving their voltage, and so they might return -EPROBE_DEFER at this stage. Our caller already attempts to resolve supplies and retry, so we shouldn't be printing this error to logs. Quiets log messages like this, on Rockchip RK3399 Gru/Kevin boards: [ 1.033057] ppvar_bigcpu: failed to get the current voltage: -EPROBE_DEFER ...

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 Restructured Text 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.
