Using memcpy_fromio() to copy device registers is not a good idea -
it can use a variable access size which can cause bus faults.
An example on how memcpy_fromio() can be avoided in get_regs:
drivers/net/ethernet/samsung/sxgbe/sxgbe_ethtool.c
Thanks for pointing me this example. I've already send a patch,
and I've used drivers/net/ethernet/freescale/gianfar_ethtool.c
as example. I hope it's a good example too.
