X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=96e74088f1da4d9a53735a4a57a4f984f86b75c6;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git net: The dev->get_stats pointer is not NULL nowadays. And so does the pointer is returns, but sysfs and netlinks still check for both cases. Signed-off-by: Pavel Emelyanov Signed-off-by: David S.
