The following changes since commit 7c53f6b671f4aba70ff15e1b05148b10d58c2837: Linux 5.11-rc3 (2021-01-10 14:34:50 -0800) are available in the Git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/helgaas/pci.git tags/pci-v5.12-changes for you to fetch changes up to e18fb64b79860cf5f381208834b8fbc493ef7cbc: Merge branch 'remotes/lorenzo/pci/misc' (2021-02-24 14:59:25 -0600) This is a resend to explain the recent dates of some of these commits. This material has all appeared in linux-next. More details at [1], but I fixed typos in commit logs and documentation and put a few patches on different topic branches, resulting in recent commit dates. The SHA1 above (e18fb64b7986) is different from yesterday's because I added my Signed-off-by to a couple patches that I missed. I apologize for the confusion.
