From 59e955edb763375f8211c009c628ca37f1bc46c0 Mon Sep 17 00:00:00 2001 From: Andrew Gallatin Date: Tue, 4 Dec 2012 10:17:15 +0000 Subject: 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 Signed-off-by: David S.
