I extracted that part out and applied it as well. I'm hoping we can restructure the rest of this as mentioned in the thread. If that's not possible, can you rebase what's left on top of this? https://git.kernel.org/pub/scm/linux/kernel/git/pci/pci.git/log/?h=reset > drivers/pci/pci-driver.c | 2 +- > drivers/pci/pci.c | 42 ++++++++++++++++++++++++++-------------- > drivers/pci/pci.h | 16 +-------------- > drivers/pci/pcie/dpc.c | 3 +-- > 4 files changed, 30 insertions(+), 33 deletions(-) > > -- > 2.39.2 >
