The irq_of_parse_and_map will return 0 as a invalid irq. Set irq_bt to -1 in this case, so that the btmrvl resume/suspend code would not try to enable/disable it. Signed-off-by:

It's much the same as what we did for mwifiex in: b9da4d22 mwifiex: avoid double-disable_irq() race "We have a race where the wakeup IRQ might be in flight while we're calling mwifiex_disable_wake() from resume(). This can leave us disabling the IRQ twice. Let's disable the IRQ and enable it in case if we have double-disabled it." Signed-off-by:

As per the comment in include/linux/net.h, the recvfrom handlers should expect msg_name to be NULL. However, bt_sock_recvmsg() is currently not checking it, which could lead to a NULL pointer dereference. The following NULL pointer dereference was produced while testing L2CAP datagram reception. Note that the kernel is tainted due to the r8723bs module being inserted. However, it seems the fix still applies. $ l2test -r -G l2test[326]: Receiving ...

The Marvell devices may have many gpio pins, and hence for wakeup on these out-of-band pins, the chip needs to be told which pin is to be used for wakeup, using an hci command. Thus, we read the pin number etc from the device tree node and send a command to the chip. Signed-off-by:

Some onboard BT chips (e.g. Marvell 8997) contain a wakeup pin that can be connected to a gpio on the CPU side, and can be used to wakeup the host out-of-band. This can be useful in situations where the in-band wakeup is not possible or not preferable (e.g. the in-band wakeup may require the USB host controller to remain active, and hence consuming more system power during system sleep). The oob gpio interrupt to be used for wakeup on the CPU side, is read from the device tree node, (using standard interrupt descriptors). A devcie tree binding document is also added for the driver. The compatible string is in compliance with Documentation/devicetree/bindings/usb/usb-device.txt Signed-off-by:

Current behaviour of "mirred redirect" action (forward) offload is a bit odd. For matched packets the action forwards them to the desired destination, but it also lets the packet duplicates to go the original way down (bridge, router, etc). That is more like "mirred mirror". Fix this by using PBS type which behaves exactly like "mirred redirect". Note that PBS does not support loopback mode.

Yuval Mintz says: ==================== qed*: Add support for PTP This patch series adds required changes for qed/qede drivers for supporting the IEEE Precision Time Protocol (PTP). Changes from previous versions: v7: Fixed Kbuild robot warnings. v6: Corrected broken loop iteration in previous version. Reduced approximation error of adjfreq. v5: Removed two divisions from the adjust-frequency loop. Resulting logic would use 8 divisions [instead of 24]. v4: Remove the loop iteration for value '0' in the qed_ptp_hw_adjfreq() implementation. v3: Use div_s64 for 64-bit divisions as do_div gives error for signed types. Incorporated review comments from Richard Cochran. - Clear timestamp resgisters as soon as timestamp is read. - Use shift operation in the place of 'divide by 16'. v2: Use do_div for 64-bit divisions. ==================== Acked-by:Richard Cochran <richardcochran@gmail.com> Signed-off-by:

Even though the port autoselection is enabled by default on AM79C970A, BNC/AUI port does not work because the link is always reported to be down. The link state reported by the chip belongs only to the TP port but the driver uses it regardless of the port used. The chip can't detect BNC/AUI link state. Disable port autoselection and use TP port by default to keep current behavior (link detection works on TP port, BNC/AUI port does not work). Implement ethtool autoneg, port and duplex configuration to allow using the BNC/AUI port. Report the TP link state only if the TP port is selected. When the port autoselection is enabled or AUI port is selected, report the link as always up. Move pcnet32_suspend() and pcnet32_clr_suspend() functions to avoid forward declarations. Signed-off-by:
