Hi Pavel,
Thank you for the patch! Yet something to improve:
[auto build test ERROR on mmotm/master]
[also build test ERROR on v4.17-rc6]
[if your patch is applied to the wrong git tree, please drop us a note to help improve the system]

# save the attached .config to linux build tree
make ARCH=i386
