I re-pushed to my queue, though if you are going to send a new version, check my repository for the titles of the patches (you need to use correct templates for the subsystems). > > Maximilian Luz (2): > platform: Fix device check for surfacepro3_button > input: soc_button_array for newer surface devices > > drivers/input/misc/soc_button_array.c | 145 ++++++++++++++++++++-- > drivers/platform/x86/surfacepro3_button.c | 38 ++++++ > 2 files changed, 171 insertions(+), 12 deletions(-) > > -- > 2.22.0 > -- With Best Regards, Andy Shevchenko
