5988aa6108 net: w5100: use dev_get_platdata()
Use the wrapper function for retrieving the platform data instead of
accessing dev->platform_data directly. This is a cosmetic change
to make the code simpler and enhance the readability.

dfd93c977d net: ethernet: remove unnecessary platform_set_drvdata()
The driver core clears the driver data to NULL after device_release
or on probe failure, since commit 0998d06310
(device-core: Ensure drvdata = NULL when no driver is bound).
Thus, it is not needed to manually clear the device driver data to NULL.

4294bebaff net: ethernet: wiznet: add CONFIG_PM_SLEEP to suspend/resume functions
Add CONFIG_PM_SLEEP to suspend/resume functions to fix the following
build warning when CONFIG_PM_SLEEP is not selected. This is because
sleep PM callbacks defined by SIMPLE_DEV_PM_OPS are only used when
the CONFIG_PM_SLEEP is enabled.

0e1effe39a net/wiznet: remove __dev* attributes
CONFIG_HOTPLUG is going away as an option.  As result the __dev*
markings will be going away.

Remove use of __devinit, __devexit_p, __devinitdata, __devinitconst,
and __devexit.

c867b55eb4 net/ethernet: remove useless is_valid_ether_addr from drivers ndo_open
If ndo_validate_addr is set to the generic eth_validate_addr
function there is no point in calling is_valid_ether_addr
from driver ndo_open if ndo_open is not used elsewhere in
the driver.

With this change is_valid_ether_addr will be called from the
generic eth_validate_addr function. So there should be no change
in the actual behavior.
