From: Colin Ian King <colin.king@xxxxxxxxxxxxx> Currently the unsigned variable tmp is being checked for an negative error return from the call to bcm_phy_read_rdb and this can never be true since tmp is unsigned. Fix this by making tmp a plain int. Addresses-Coverity: ("Unsigned compared against 0") Fixes: 4406d36dfdf1 ("net: phy: bcm54140: add hwmon support") Signed-off-by: Colin Ian King <colin.king@xxxxxxxxxxxxx> --- drivers/net/phy/bcm54140.c | 6 ++++-- 1 file changed, 4 insertions(+), 2 deletions(-) diff --git a/drivers/net/phy/bcm54140.c b/drivers/net/phy/bcm54140.c index aa854477e06a..7341f0126cc4 100644 --- a/drivers/net/phy/bcm54140.c +++ b/drivers/net/phy/bcm54140.c @@ -191,7 +191,8 @@ static int bcm54140_hwmon_read_alarm(struct device *dev, unsigned int bit, static int bcm54140_hwmon_read_temp(struct device *dev, u32 attr, long *val) { struct phy_device *phydev = dev_get_drvdata(dev); - u16 reg, tmp; + u16 reg; + int tmp; switch (attr) { case hwmon_temp_input: @@ -224,7 +225,8 @@ static int bcm54140_hwmon_read_in(struct device *dev, u32 attr, int channel, long *val) { struct phy_device *phydev = dev_get_drvdata(dev); - u16 bit, reg, tmp; + u16 bit, reg; + int tmp; switch (attr) { case hwmon_in_input: -- 2.25.1
