[ Upstream commitb39f3bb9f5] If tcs3472_probe() fails after enabling the chip (by writing PON | AEN to the ENABLE register), the error paths return without powering down the device. Add an 'error_powerdown' label at the end of the cleanup chain that calls tcs3472_powerdown() to power down the chip. The existing label cascade is rerouted to fall through to the new label. Move tcs3472_powerdown() above tcs3472_probe() so the probe can call it without a forward declaration. Found by code inspection while reviewing the probe error paths in preparation for the devm_ conversion.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
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.
