ACPI platforms might also have a reset GPIO and regulators, move the code to get these outside of the if (!is_acpi_node(fwnode)) check. This also removes the is_acpi_node(fwnode) checks from ov08x40_power_on() / ov08x40_power_off() both the GPIO hand the clk frameworks functions used there will happily accept the NULL pointer returned from the optional get() functions when there is no reset GPIO / no clk. While moving the code around also at error logging to the error exit path for getting the reset GPIO.

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 reStructuredText 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.
