The device_property_read_u8_array() call should not fail because it is preceded with device_property_count_u8() and check for number of readable u8 values. However the code is more obvious and easier to read if the return value of device_property_read_u8_array() is checked. Otherwise reader needs to investigate whether really there is no risk of using random stack values of 'rcomp' variable.

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.
