During boot we call riscv_of_processor_hartid() for each hart that we add to the possible cpus list. Repeating the call again here is not required, if we iterate over the list of possible CPUs, rather than the list of all CPUs. The call to of_property_read_string() for "riscv,isa" cannot fail either, as it has previously succeeded in riscv_of_processor_hartid(), but leaving in the error checking makes the operation of the loop more obvious & provides leeway for future refactoring of riscv_of_processor_hartid().

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.
