Hi,
Awesome implimentaion of SPI driver using Raspberry pi.
I started to impliment the same ,while implimenting this in raspberry Pi 4 , i stuck with the problem of execution of Makefile. Below is the error message:

Actually i have found a temporary solution *Use the older version of the kernel ie. 5.10._____ * *dont use 6._____* *i am working on the code for the 6.____ version* there* is an issue in the .c code when the version changes.* If u have any further discussions or any issues or any lead do contact me on linkedin or github itself
