ethtool: remove unnecessary check in ethtool_get_regs()
We recently changed this function in commit f9fc54d313fa ("ethtool: check the return value of get_regs_len") such that if "reglen" is zero we return directly. That means we can remove this condition as well. Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com> Signed-off-by: David S. Miller <davem@davemloft.net>
