Subject: [PATCH 2/2] Input: soc_button_array - Suppress power button presses
|
|
|
51a2ae7 |
during suspend
|
|
|
51a2ae7 |
|
|
|
51a2ae7 |
If the power-button is pressed to wakeup the laptop/tablet from suspend
|
|
|
51a2ae7 |
and we report a KEY_POWER event to userspace when woken up this will cause
|
|
|
51a2ae7 |
userspace to immediately suspend the system again which is undesirable.
|
|
|
51a2ae7 |
|
|
|
51a2ae7 |
This commit sets the new no_wakeup_events flag in the gpio_keys_button
|
|
|
51a2ae7 |
struct for the power-button suppressing the undesirable KEY_POWER input
|
|
|
51a2ae7 |
events on wake-up.
