If the power-button is pressed to wakeup the laptop/tablet from suspend and we report a KEY_POWER event to userspace when woken up this will cause userspace to immediately suspend the system again which is undesirable. This commit sets the new suppress_evdev_events_on_wakeup flag in the gpio_keys_button struct for the power-button suppressing the undesirable KEY_POWER input events on wake-up. Signed-off-by: Hans de Goede <hdegoede@redhat.com> --- Changes in v3: -Adjust for the renaming of the flag to suppress_evdev_events_on_wakeup -Explicitly init the flag for all members of the soc_button_PNP0C40 array --- drivers/input/misc/soc_button_array.c | 14 +++++++++----- 1 file changed, 9 insertions(+), 5 deletions(-)
