[ Upstream commit3b25528e1e] The devicetree binding lists the phy phy as optional. As such, the driver should not bail out if it can't find a regulator. Instead it should just skip the remaining regulator related code and continue on normally. Skip the remainder of phy_power_on() if a regulator supply isn't available. This also gets rid of the bogus return code.

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.
