Commit8dce89a1c2("clk: tegra: Don't warn for PLL defaults unnecessarily") changed the tegra210_pllcx_set_defaults() function causing the PLL to always be reset regardless of whether it is in-use. This function was changed so that resetting of the PLL will only be skipped if the PLL is enabled AND 'pllcx->params->defaults_set' is not true. However, the 'pllcx->params->defaults_set' is always true and hence, the PLL is now always reset. This causes the boot to fail on the Tegra210 Smaug where the PLL is already enabled and in-use. Fix this by only resetting the PLL if not in-use and only printing the warning that the defaults are not set after we have checked the default settings.

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.
