| |
From: Colin Ian King <colin.king@canonical.com>
The comparison of the u16 priv->phy_addr < 0 is always false because phy_addr is unsigned. Fix this by assigning the return from the call to function asix_read_phy_addr to int ret and using this for the less than zero error check comparison.
Addresses-Coverity: ("Unsigned compared against 0") Fixes: 7e88b11a862a ("net: usb: asix: refactor asix_read_phy_addr() and handle errors on return") Signed-off-by: Colin Ian King <colin.king@canonical.com> --- drivers/net/usb/ax88172a.c | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-)
