I'm sorry that I missed this patch. I normally work from patchwork (https://patchwork.ozlabs.org/project/linux-pci/list/), and it apparently doesn't pick up patches that are attached (or maybe it just misses gzipped ones). Can you please repost this as plain-text email with the patch included inline, with a changelog and Signed-off-by? Then patchwork should pick it up and I won't forget about it. For details about Signed-off-by, etc, see https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/Documentation/process/submitting-patches.rst Bjorn
