If build kernel without "O=dir", below error will be seen:
In file included from drivers/tee/optee/optee_trace.h:67,
from drivers/tee/optee/call.c:18:
./include/trace/define_trace.h:95:42: fatal error: ./optee_trace.h: No such
file or directory
95 | #include TRACE_INCLUDE(TRACE_INCLUDE_FILE)
| ^
compilation terminated.
Fix it by adding below line to Makefile:
CFLAGS_call.o := -I$(src)
Tested with and without "O=dir", both can build successfully.
