commit44a146a44fupstream. When VCNL4035 is enabled and IIO_BUFFER is disabled, it results in the following Kbuild warning: WARNING: unmet direct dependencies detected for IIO_TRIGGERED_BUFFER Depends on [n]: IIO [=y] && IIO_BUFFER [=n] Selected by [y]: - VCNL4035 [=y] && IIO [=y] && I2C [=y] The reason is that VCNL4035 selects IIO_TRIGGERED_BUFFER without depending on or selecting IIO_BUFFER while IIO_TRIGGERED_BUFFER depends on IIO_BUFFER. This can also fail building the kernel. Honor the kconfig dependency to remove unmet direct dependency warnings and avoid any potential build failures.

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.
