[ Upstream commit bc2e9578baed90f36abe6bb922b9598a327b0555 ]
The header file spi.h in include/uapi/linux/spi is needed for spidev.h, so we also need make a symbolic link to it to eliminate the error message as below:
In file included from spidev_test.c:24: include/linux/spi/spidev.h:28:10: fatal error: linux/spi/spi.h: No such file or directory 28 | #include <linux/spi/spi.h> | ^~~~~~~~~~~~~~~~~ compilation terminated.
