Commit7fb59e940f("ASoC: codecs: dmic: Make number of channels configurable") introduces an optional property to the device tree to specify the number of DMIC channels. dmic_codec_probe() uses of_property_read_u32() to read the DT value, and expects a return value of -ENOENT when the property does not exist. This expectation is incorrect, the actual value returned in this case is -EINVAL (see of_find_property_value_of_size(), which is called under the hood). Check for -EINVAL instead.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
