commit f061e2be8689057cb4ec0dbffa9f03e1a23cdcb2 upstream. The WM8904_ADC_TEST_0 register is modified as part of updating the OSR controls but does not have a cache default, leading to errors when we try to modify these controls in cache only mode with no prior read: wm8904 3-001a: ASoC: error at snd_soc_component_update_bits on wm8904.3-001a for register: [0x000000c6] -16 Add a read of the register to probe() to fill the cache and avoid both the error messages and the misconfiguration of the chip which will result.

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.
