Previously enabled clks are only disabled if clk_prepare_enable() fails. However, there are other error paths were the previously enabled clocks are not disabled. To fix the problem, fsl_disable_clocks() now takes the number of clocks that shall be disabled + unprepared. For existing calls were all clocks were already successfully prepared + enabled, DMAMUX_NR is passed to disable + unprepare all clocks. In error paths were only some clocks were successfully prepared + enabled the loop counter is passed, in order to disable + unprepare all successfully prepared + enabled clocks.

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.
