The original code used the wrong parameter to clear tx_atten[]. It passed the number of elements instead of sizeof() the array to memset.
The other potential issue was that cphy_base[] wasn't cleared. I'm not sure if that was a real problem or not, but I have cleared it in my patch. Instead of using memset(), this patch uses empty initializers as a cleanup. Signed-off-by: Dan Carpenter <[email protected]> --- v2: used {} initialization instead of memset. I also just went ahead and cleared cphy_base[]. diff --git a/drivers/ata/sata_highbank.c b/drivers/ata/sata_highbank.c index 7f5e5d9..ea3b3dc 100644 --- a/drivers/ata/sata_highbank.c +++ b/drivers/ata/sata_highbank.c @@ -343,13 +343,11 @@ static int highbank_initialize_phys(struct device *dev, void __iomem *addr) { struct device_node *sata_node = dev->of_node; int phy_count = 0, phy, port = 0, i; - void __iomem *cphy_base[CPHY_PHY_COUNT]; - struct device_node *phy_nodes[CPHY_PHY_COUNT]; - u32 tx_atten[CPHY_PORT_COUNT]; + void __iomem *cphy_base[CPHY_PHY_COUNT] = {}; + struct device_node *phy_nodes[CPHY_PHY_COUNT] = {}; + u32 tx_atten[CPHY_PORT_COUNT] = {}; memset(port_data, 0, sizeof(struct phy_lane_info) * CPHY_PORT_COUNT); - memset(phy_nodes, 0, sizeof(struct device_node*) * CPHY_PHY_COUNT); - memset(tx_atten, 0xff, CPHY_PORT_COUNT); do { u32 tmp; -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
