The reading of the pressure and humidity value, requires an update of the
t_fine variable which happens by reading the temperature value.
So the bme680_read_{press/humid}() functions of the above sensors are
internally calling the equivalent bme680_read_temp() function in order to
update the t_fine value. By just looking at the code this relation is a
bit hidden and is not easy to understand why those channels are not
independent.
This commit tries to clear these thing a bit by splitting the
bme680_{read/compensate}_{temp/press/humid}() to the following:
i. bme680_read_{temp/press/humid}_adc(): read the raw value from the
sensor.
ii. bme680_calc_t_fine(): calculate the t_fine variable.
iii. bme680_get_t_fine(): get the t_fine variable.
iv. bme680_compensate_{temp/press/humid}(): compensate the adc values and
return the calculated value.
v. bme680_read_{temp/press/humid}(): combine calls of the aforementioned
functions to return the requested value.

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.
