From 42851e88a7556e525a5527d46c3763830d8fdd2e Mon Sep 17 00:00:00 2001 From: Claudiu Manoil Date: Tue, 14 Jan 2014 15:35:00 +0200 Subject: [PATCH] gianfar: Fix portabilty issues for ethtool and ptp Fixes unhandled register write in gianfar_ethtool.c. Fixes following endianess related functional issues, reported by sparse as well, i.e.: gianfar_ethtool.c:1058:33: warning: incorrect type in argument 1 (different base types) expected unsigned int [unsigned] [usertype] value got restricted __be32 [usertype] ip4src gianfar_ethtool.c:1164:33: warning: restricted __be16 degrades to integer gianfar_ethtool.c:1669:32: warning: invalid assignment: ^= left side has type restricted __be16 right side has type int Solves all the sparse warnings for mixig normal pointers with __iomem pointers for gianfar_ptp.c, i.e.: gianfar_ptp.c:163:32: warning: incorrect type in argument 1 (different address spaces) expected unsigned int [noderef] *addr got unsigned int * Signed-off-by: Claudiu Manoil Signed-off-by: David S.
