If anyone has any objections, please let me know. ------------------ From: Nikhil P. Rao [ Upstream commit 73608de7e59246b4b533c1ffaee158a7048e186e ] pdsc_reset_prepare() called pci_release_regions() unconditionally, but only PFs call pci_request_regions() (pdsc_init_pf). On a VF FLR this makes the kernel warn "Trying to free nonexistent resource".
