[ Upstream commite29e24bdab] of_property_read_u32_array takes the number of elements to read as last argument. This does not always need to be 4 (sizeof(u32)) but should instead be the size of the array in DT as read just above with of_property_count_elems_of_size. To not make such an error go unnoticed again the driver now bails accordingly when of_property_read_u32_array returns an error. Surprisingly the indentation of newlined arguments is lining up again after prepending `rc = `.

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.
