[ Upstream commit771725efe5] When the 'ti,gpio-config' property is not defined, the device_property_count_u32() will return an error, rather than zero. The current check, only handles a return value of zero, which assumes that the property is defined and has nothing defined. This change extends the check to also check for an error case (most likely to be hit by the case that the 'ti,gpio-config' is not defined). In case that the 'ti,gpio-config' and the returned 'gpio_count' is not correct, there is a 'if (gpio_count != ADCX140_NUM_GPIO_CFGS)' check, a few lines lower that will return -EINVAL. This means that someone tried to define 'ti,gpio-config', but with the wrong number of GPIOs.

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.
