parentperf arm-spe: Refactor payload size calculation (diff)
perf arm-spe: Refactor arm_spe_get_events()
In function arm_spe_get_events(), the event packet's 'index' is assigned as payload length, but the flow is not directive: it firstly gets the packet length from the return value of arm_spe_get_payload(), the value includes header length (1) and payload length: int ret = arm_spe_get_payload(buf, len, packet); and then reduces header length from packet length, so finally get the payload length: packet->index = ret - 1; To simplify the code, this patch directly assigns payload length to event packet's index; and at the end it calls arm_spe_get_payload() to return the payload value.
