Unfortunately, this member is not established on all architectures, which leads to a kernel oops. Skipping the entire block that uses the self member to determine the bridge vendor will only affect RTL8192DE devices as that driver sets the ASPM support flag differently when the bridge vendor is Intel. If the self member is available, there is no functional change. This patch fixes Bugzilla No. 40212.

If a write is held and followed by a delay, the delay means nothing because the write may not have reached hardware (maybe even not until the next read) Signed-off-by: Jesse Brandeburg Tested-by: Aaron Brown Signed-off-by: Jeff Kirsher --- drivers/net/e1000/e1000_ethtool.c | 6 ++++++ drivers/net/e1000/e1000_hw.c | 3 +++ drivers/net/e1000e/es2lan.c | 2 ++ drivers/net/e1000e/ethtool.c | 9 +++++++++ drivers/net/e1000e/ich8lan.c | 4 ++++ drivers/net/e1000e/lib.c | 1 + drivers/net/e1000e/phy.c | 2 ++ drivers/net/igb/e1000_nvm.c | 1 + drivers/net/igb/igb_ethtool.c | 5 +++++ drivers/net/igb/igb_main.c | 2 ++ drivers/net/igbvf/netdev.c | 2 ++ drivers/net/ixgb/ixgb_ee.c | 9 +++++++++ drivers/net/ixgb/ixgb_hw.c | 2 ++ drivers/net/ixgbe/ixgbe_common.c | 1 + drivers/net/ixgbe/ixgbe_ethtool.c | 5 +++++ drivers/net/ixgbe/ixgbe_main.c | 1 + drivers/net/ixgbe/ixgbe_phy.c | 3 +++ drivers/net/ixgbe/ixgbe_x540.c | 1 + 18 files changed, 59 insertions(+) (limited to 'drivers/net') diff --git a/drivers/net/e1000/e1000_ethtool.c b/drivers/net/e1000/e1000_ethtool.c index c5f0f04219f3..5548d464261a 100644 --- a/drivers/net/e1000/e1000_ethtool.c +++ b/drivers/net/e1000/e1000_ethtool.c @@ -838,6 +838,7 @@ static int e1000_intr_test(struct e1000_adapter *adapter, u64 *data) /* Disable all the interrupts */ ew32(IMC, 0xFFFFFFFF);
