Please describe your issue below:
1、RK3588接了两个ov9282模组同时打开抓图
2、使用一段时间后出现v4l2指令抓图time out，目前没有发现规律
kernel 关键log
[ 150.941949] rkcif-mipi-lvds2: not active buffer, use dummy buffer, mipi/lvds stream0
[ 150.942021] rkcif-mipi-lvds3: not active buffer, use dummy buffer, mipi/lvds stream[0]
使用一段时间后再重新v4l2抓流就time out了，
报错后重新抓还是不行，报这个错误。
log是我重启机器后抓的，重启后用v4l2抓图也是不行，配置下发和stream on流程都是没有问题的。
之前也怀疑过是不是硬件问题，但是刷机之后就可以了，使用一段时间后又会出现这个问题。
出现这个现象后不可逆，相机就不能用了。
