The driver returns -ENODEV when the firmware battmrg service hasn't
started yet, while per-se -ENODEV is fine, we usually use -EAGAIN to
tell the user to retry again later. And the power supply core uses
-EGAIN when the device isn't initialized, let's use the same return.
This notably causes an infinite spam of:
thermal thermal_zoneXX: failed to read out thermal zone (-19)
because the thermal core doesn't understand -ENODEV, but only
considers -EAGAIN as a non-fatal error.
While it didn't appear until now, commit [1] fixes thermal core
and no more ignores thermal zones returning an error at first
temperature update.

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.
