    wifi: ath12k: do not dump SRNG statistics during resume · 8591b2ba
    Baochen Qiang authored
    Both the firmware reset feature and the power management
    suspend/resume feature share common power-down and power-up
    functionality. One aspect of the power-up functionality is
    the handling of the ATH12K_QMI_EVENT_FW_INIT_DONE event.
    When this event is received, a call is made to
    ath12k_hal_dump_srng_stats(), with the purpose to collect
    information that may be useful in debugging the cause of a
    firmware reset.
    
    Unfortunately, since this functionality is shared between
    both the firmware reset path and the power management
    resume path, the kernel log is flooded with messages during
    resume. Since these messages are not useful during resume,
    and in fact can be confusing and can increase the time it
    takes to resume, update the logic to only call
    ath12k_hal_dump_srng_stats() during firmware reset.
