[ Upstream commit 104d32bd81f620bb9f67fbf7d1159c414e89f05f ]
In stmpe_probe(), if some regulator_enable() calls fail, probing continues
and there is only a dev_warn().
So, if stmpe_probe() is called the regulator may not be enabled. It is
cleaner to test it before calling regulator_disable() in the remove
function.
Fixes: 9c9e321455 ("mfd: stmpe: add optional regulators")

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.
