From: Krzysztof Wilczynski <kw@linux.com>
[ Upstream commit 7f1c62c443a453deb6eb3515e3c05650ffe0dcf0 ]
Do not use printk_ratelimit() in drivers/pci/pci.c as it shares the rate limiting state with all other callers to the printk_ratelimit().
Add pci_info_ratelimited() (similar to pci_notice_ratelimited() added in the commit a88a7b3eb076 ("vfio: Use dev_printk() when possible")) and use it instead of printk_ratelimit() + pci_info().
