myri10ge: fix most sparse warnings
- convert remaining htonl/ntohl +__raw_read/__raw_writel to swab32 + readl/writel - add missing __iomem qualifier in myri10ge_open() - fix dubious: x & !y warning by switching from logical to bitwise not The swab32 conversion fixes a bug in myri10ge_led() where big-endian machines would write the wrong pattern. The only remaining warning (lock context imbalance) is due to the use of __netif_tx_trylock(), and cannot easily be fixed. Signed-off-by: Andrew Gallatin <gallatin@myri.com> Signed-off-by: David S. Miller <davem@davemloft.net>
