[ Upstream commite4a7dca5de] In the ioctl_event_ctl() SWITCHTEC_IOCTL_EVENT_IDX_ALL case, we call event_ctl() several times with the same "ctl" struct. Each call clobbers ctl.flags, which leads to the problem that we may not actually enable or disable all events as the user requested. Preserve the event flag value with a temporary variable.
