adv7511 probe may need to be attempted multiple times before no -EPROBE_DEFER is returned. Currently, every such probe results in an error message: [ 4.534229] adv7511 1-003d: failed to find dsi host [ 4.580288] adv7511 1-003d: failed to find dsi host This is misleading, as there is no error and probe deferral is normal behavior. Fix this by using dev_err_probe that will suppress -EPROBE_DEFER errors. While at it, we touch all dev_err in the probe path. This makes the code more concise and included the error code everywhere to aid user in debugging.

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.
