Looking at the next patch 0x131c is TP_HKEY_EV_DOUBLETAP_TOGGLE and 0x131a is
TP_HKEY_EV_AMT_TOGGLE based on this please change this to:

  		KEY_NOTIFICATION_CENTER,	/* Notification Center */
  		KEY_PICKUP_PHONE,		/* Answer incoming call */
  		KEY_HANGUP_PHONE,		/* Decline incoming call */
		KEY_UNKNOWN,			/* TP_HKEY_EV_AMT_TOGGLE handled in driver, 0x31a */
		KEY_UNKNOWN,			/* ?, 0X31b */
		KEY_UNKNOWN,			/* TP_HKEY_EV_DOUBLETAP_TOGGLE handled in driver, 0x31c */
		KEY_SYS_DEBUG_INFO,             /* System debug info, 0x31d */
		},

Regards,

Hans
