2013-03-15drivers:net: Remove dma_alloc_coherent OOM messagesJoe Perches1-7/+2
I believe these error messages are already logged on allocation failure by warn_alloc_failed and so get a dump_stack on OOM. Remove the unnecessary additional error logging. Around these deletions: o Alignment neatening. o Remove unnecessary casts of dma_alloc_coherent. o Hoist assigns from ifs. Signed-off-by: Joe Perches <joe@perches.com> Signed-off-by: David S.

2013-02-04ethernet: Remove unnecessary alloc/OOM messages, alloc cleanupsJoe Perches1-6/+4
alloc failures already get standardized OOM messages and a dump_stack. Convert kzalloc's with multiplies to kcalloc. Convert kmalloc's with multiplies to kmalloc_array. Fix a few whitespace defects. Convert a constant 6 to ETH_ALEN. Use parentheses around sizeof. Convert vmalloc/memset to vzalloc. Remove now unused size variables.

2013-01-14net: phy: remove flags argument from phy_{attach, connect, connect_direct}Florian Fainelli1-1/+1
The flags argument of the phy_{attach,connect,connect_direct} functions is then used to assign a struct phy_device dev_flags with its value. All callers but the tg3 driver pass the flag 0, which results in the underlying PHY drivers in drivers/net/phy/ not being able to actually use any of the flags they would set in dev_flags. This patch gets rid of the flags argument, and passes phydev->dev_flags to the internal PHY library call phy_attach_direct() such that drivers which actually modify a phy device dev_flags get the value preserved for use by the underlying phy driver.

2012-10-07drivers/net/ethernet/renesas/sh_eth.c: fix error return codePeter Senna Tschudin1-0/+1
The function sh_eth_drv_probe() return 0 for success and negative value for most of its internal tests failures. There is one exception that is error case going to out_release:. For this error case, the function abort its success execution path, but returns non negative value, making it difficult for a caller function to notice the error. This patch fixes the error case that do not return negative value. This was found by Coccinelle, but the code change was made by hand. This patch is not robot generated. A simplified version of the semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> ( if@p1 (\(ret < 0\|ret != 0\)) { ... return ret; } | ret@p1 = 0 ) ... when != ret = e1 when != &ret *if(...) { ... when != ret = e2 when forall return ret; } // </smpl> Signed-off-by: Peter Senna Tschudin <peter.senna@gmail.com> Signed-off-by: David S.

2012-02-07net: sh_eth: fix skb_over_panic happenYoshihiro Shimoda2-4/+3
When this GETHER controller received a large frame (about 1800 bytes or more), skb_over_panic() happened. This is because the previous driver set the RFLR to 0x1000 (4096 bytes) and the skb allocate size is smaller than 4096 bytes. So, the controller accepted such a frame. The controller can discard a large frame by the RFLR setting. So, the patch modifies the value of RFLR to mtu + ETH_HLEN + VLAN_HLEN + ETH_FCS_LEN.
