In dpc_probe(), we set dpc->rp_log_size to zero if we think the hardware reports an invalid size. In this case, we could have dpc->rp_extensions set but dpc->rp_log_size == 0, and we should print the basic RP PIO registers but not the variable-size portion. We already checked for dpc->rp_log_size < 4 above, so this patch is just for consistency of style. No functional change intended.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
