| Subject: [PATCH 2/2] Input: soc_button_array - Suppress power button presses
 | |
|  during suspend
 | |
| 
 | |
| 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 no_wakeup_events flag in the gpio_keys_button
 | |
| struct for the power-button suppressing the undesirable KEY_POWER input
 | |
| events on wake-up.
