The gpio driver runs into issues on v1 gpio blocks, as the db_clk
and the whole extended debounce support is only ever defined on v2.
So checking for the IS_ERR on the db_clk is not enough, as it will
be NULL on v1.
Fix this by adding the needed condition for v2 first before checking
the existence of the db_clk.
This caused my rk3288-veyron-pinky to enter a reboot loop when it
tried to enable the power-key as adc-key device.

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.
