[ Upstream commit84b4bd7e0d] When the ov2680_power_on() "sensor soft reset failed" path is hit during probe() the WARN() about putting an enabled regulator at drivers/regulator/core.c:2398 triggers 3 times (once for each regulator), filling dmesg with backtraces. Fix this by properly disabling the regulators on ov2680_power_on() errors.

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.
