commitb9820a3169upstream. The error pointer from devm_reset_control_get_optional_shared() is not propagated. One of the most common problem scenarios is it returns -EPROBE_DEFER when the reset controller has not probed yet. In this case, the probe of the reset consumer should be deferred.

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.
