PCI/bwctrl: Remove unused pcie_bwctrl_lbms_rwsem Builds with CONFIG_PREEMPT_RT=y get the following build error: drivers/pci/pcie/bwctrl.c:56:22: error: ‘pcie_bwctrl_lbms_rwsem’ defined but not used [-Werror=unused-variable] Therefore, remove this unused variable. Perhaps this should be folded into the commit shown below. Fixes: 0238f352a63a ("PCI/bwctrl: Replace lbms_count with PCI_LINK_LBMS_SEEN flag") Signed-off-by: Paul E.
