Switch's BARs are not used by the portdrv driver, but they are still considered as immovable until the .rescan_prepare() and .rescan_done() hooks are added. Add these hooks to increase chances to allocate new BARs. Signed-off-by: Sergey Miroshnichenko <redacted> --- drivers/pci/pcie/portdrv_pci.c | 11 +++++++++++ 1 file changed, 11 insertions(+)
