2008-09-24gianfar: free/iounmap memory after an error in mii bus initializationAndy Fleming
Recent changes to MII bus initialization code added exit points which didn't free or iounmap the bus before returning. Addresses http://bugzilla.kernel.org/show_bug.cgi?id=11372.

2008-09-24ne.c: fix rmmod, platform driver improvementsDavid Fries
Removing the module would cause a kernel oops as platform_driver_probe failed to detect a device and unregistered the platform driver on module init, and cleanup_module would unregister the already unregistered driver. The suspend and resume functions weren't being called. platform_driver support was added earlier, but without any platform_device_register* calls I don't think it was being used. Now all devices are registered using platform_device_register_simple and pointers are kept to unregister the ones that the probe failed for or unregister all devices on module shutdown. init_module no longer calls ne_init to reduce confusion (and multiple unregister paths that caused the rmmod oops). With the devices now registered they are added to the platform driver and get suspend and resume events. netif_device_detach(dev) was added before unregister_netdev(dev) when removing the region as occationally I would see a race condition where the device was still being used in unregister_netdev.

2008-09-24gianfar: Fix error in mdio reset timeoutTrent Piepho
The loop with the timeout used "while (... && timeout--)", which means than when the timeout occurs, "timeout" will be -1 after the loop has exited. The code that checks if the looped exited because of a timeout used "if (timeout <= 0)". Seems ok, except timeout is unsigned, and (unsigned)-1 isn't less than zero! Using "--timeout" in the loop fixes this problem, as now "timeout" will be 0 when the loop times out. This also fixes a bug in the existing code, where it will erroneously think a timeout occurred if the condition the loop was waiting for is satisfied on the final iteration before a timeout.

2008-09-24e1000e: remove failed request for sw/fw/hw flagBruce Allan
When the driver fails to acquire the control flag used to serialize NVM and PHY accesses between the driver, firmware and hardware, remove the request for the flag otherwise the hardware might grant the flag when it becomes available but the driver will not release the flag. This could cause the firmware to prevent the driver getting the flag for all future attempts.

2008-09-24enic: bug fix: don't set netdev->name too earlyScott Feldman
Bug fix: don't set netdev->name early before netdev registration. Setting netdev->name early with dev_alloc_name() would occasionally cause netdev registration to fail returning error that device was already registered. Since we're using netdev->name to name MSI-X vectors, we now need to move the request_irq after netdev registartion, so move it to ->open.
