[ Upstream commit 3ca232df9921f083c3b37ba5fbc76f4d9046268b ] pwm_vibrator_stop disables the regulator, but it can be called from multiple places, even when the regulator is already disabled. Fix this by using regulator_is_enabled check when starting and stopping device.

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.
