Switch camera the screen black

While test switching camera, the screen got black, and it happened once in a while. I have got the log, it shows kernel error as below:

pm_qos_update_request() called for unknown object------------[ cut here ]------------WARNING: CPU: 3 PID: 17637 at /fibocom/dailybuild/workspace/SA6125_car_la10_AL656S_R600_GAC/build/sa6125-car-r600/android/kernel/msm-4.14/kernel/power/qos.c:685 pm_qos_update_request+0x44/0x54Modules linked in: gsl wlan(O) cpe_lsm_dlkm(O) machine_dlkm(O) wcd934x_dlkm(O) wcd9335_dlkm(O) mbhc_dlkm(O) wcd9xxx_dlkm(O) wcd_cpe_dlkm(O) tx_macro_dlkm(O) rx_macro_dlkm(O) va_macro_dlkm(O) wsa_macro_dlkm(O) swr_ctrl_dlkm(O) bolero_cdc_dlkm(O) wsa881x_dlkm(O) wcd_core_dlkm(O) stub_dlkm(O) wcd_spi_dlkm(O) hdmi_dlkm(O) swr_dlkm(O) pinctrl_wcd_dlkm(O) usf_dlkm(O) native_dlkm(O) platform_dlkm(O) q6_dlkm(O) adsp_loader_dlkm(O) apr_dlkm(O) snd_event_dlkm(O) q6_notifier_dlkm(O) q6_pdr_dlkm(O) wglink_dlkm(O) msm_11ad_proxyCPU: 3 PID: 17637 Comm: HwBinder:17484_ Tainted: G S      W  O    4.14.117 #1Hardware name: Qualcomm Technologies, Inc. trinket pm6125 QRD (DT)task: 0000000010bd2e11 task.stack: 0000000013011a61pc : pm_qos_update_request+0x44/0x54....Call trace:pm_qos_update_request+0x44/0x54msm_pm_qos_update_request+0x90/0x9c

The last called function is pm_qos_update_request.It seems to be a kernel error in this function

        if (!pm_qos_request_active(req)) {            WARN(1, KERN_ERR "pm_qos_update_request() called for unknown object\n");            return;        }

I'm not sure if this lead to switch camera(I have 3 cameras) error.

Besides, when the screen got black, the log shows below:

msm_vfe47_reset_hardware: failed: reset timeout+nau88c22_reg_write!msm_isp_open_node: reset timeout

Anyone who can help me?
