From 08be2836df0b07aac65fea583b762335569fd47a Mon Sep 17 00:00:00 2001 From: "Cormier, Jonathan" Date: Wed, 21 May 2014 13:08:52 -0400 Subject: [PATCH] phy: fix create_phy_by_mask for when its given an actual search mask get_phy_id returns -EIO when it can't read from a phy at a given addr. This would cause create_phy_by_mask to return prematurely before it had tested the other addresses in the provided mask. Example usage: Replace phydev = phy_connect(bus, phy_addr, dev, phy_if) with phydev = phy_find_by_mask(bus, phy_mask, phy_if) if (phydev) phy_connect_dev(phydev, dev); Signed-off-by: Cormier, Jonathan Cc: Joe Hershberger --- drivers/net/phy/phy.c | 4 +--- 1 file changed, 1 insertion(+), 3 deletions(-) diff --git a/drivers/net/phy/phy.c b/drivers/net/phy/phy.c index 230ed97dd1..aac85c4d09 100644 --- a/drivers/net/phy/phy.c +++ b/drivers/net/phy/phy.c @@ -609,10 +609,8 @@ static struct phy_device *create_phy_by_mask(struct mii_dev *bus, while (phy_mask) { int addr = ffs(phy_mask) - 1; int r = get_phy_id(bus, addr, devad, &phy_id); - if (r < 0) - return ERR_PTR(r); /* If the PHY ID is mostly f's, we didn't find anything */ - if ((phy_id & 0x1fffffff) != 0x1fffffff) + if (r == 0 && (phy_id & 0x1fffffff) != 0x1fffffff) return phy_device_create(bus, addr, phy_id, interface); phy_mask &= ~(1 << addr); } -- 2.39.5
