Dan Carpenter eba697b3c3 Input: iqs7222 - propagate some error codes correctly
If fwnode_property_count_u32() returns a negative error code then,
because of type promotion, the "count > ARRAY_SIZE(pins)" condition
will be true.  The negative "count" is type promoted to a high unsigned
size_t value.

That means the "else if (count < 0)" condition will always be false and
we don't print that error message or propagate the error code from
fwnode_property_count_u32() as intended.

Fix this by re-ordering the checks so that we check for negative first.

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.
