Hi Mustafa

one can try to debug it using Chapter 20 MIPI CSI2 Driver attached Linux Manual and

AN4553 Using Open Source Debugging Tools for Linux on i.MX Processors

Thanks @igorpadykov the error massage  meanings are simply is mentioned at errno-base.h  in the system. After look at this I write pr_info(); function to the device driver  to figure out at which part I have faced with the problem .
