> This patch set comprises some one-liners to fix issues with repeated
> loading and unloading of a modular mv643xx_eth driver.
>
> First two patches take care of the periodic port statistic timer, that
> updates statistics by reading port registers using add_timer/mod_timer.
>
> Patch 1 moves timer re-schedule from mib_counters_update to the timer
> callback. As mib_counters_update is also called from non-timer context,
> this ensures the timer is reactivated from timer context only.
>
> Patch 2 moves initial timer schedule from _probe() time to right before
> the port is actually started as the corresponding del_timer_sync is at
> _stop() time. This fixes a regression, where unloading the driver from a
> non-started eth device can cause the timer to access deallocated mem.
>
> Patch 3 adds an assignment of the ports device_node to the corresponding
> self-created platform_device. This is required to allow fixups based on
> the device_node's compatible string later. Actually, it is also a potential
> regression because we already check compatible string for Kirkwood, but
> does not (yet) rely on the fixup.
>
> All patches are based on v3.12-rc3 and have been tested on Kirkwood-based
> Seagate Dockstar.
>
> Patches 1 and 2 can also possibly queued up for -stable.
Series applied, patch #1 and #2 queued up for -stable, thanks!
