Fix the issue that mic type detection error after resume. The microphone type detection procedure will recognize testing signal on JKSLV pin, but before the procedure, JKSLV already had supply voltage, that results in the failure. Therefore, the patch turns off the power and reset the jack type configuration before suspend. Then redo the jack detection procedure after resume. The patch help to fix the issue as follows: Google issue 37973093: CTIA/OMTP jack type detection failure after resume Reported Issue Chrome OS Version : ChromeOS R59-9460.13.0 Type of hardware : DVT sample What steps will reproduce the problem?

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.
