I noticed below error msg with sdhci-pxav3 on some berlin platforms: [.....] sdhci-pxav3 f7ab0000.sdhci failed to add host It is due to getting related vmmc or vqmmc regulator returns -EPROBE_DEFER. It doesn't matter at all but it's confusing. >From another side, if driver probing fails and the error number isn't -EPROBE_DEFER, the core will tell us something as below: [.....] sdhci-pxav3: probe of f7ab0000.sdhci failed with error -EXX So it's not necessary to emit error msg if sdhci_add_host() fails. And some other sdhci host drivers also have this issue, let's fix them together.

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.
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.
