If no RARP, BOOTP, or DHCP response is received, ic_dev is never set, causing a NULL pointer dereference in ic_close_devs(): Sending DHCP requests ...... timed out! Unable to handle kernel NULL pointer dereference at virtual address 00000004 To fix this, add a check to avoid dereferencing ic_dev if it is still NULL. Signed-off-by:
