The compilation with gcc-6.3.0 and EXTRA_CFLAGS=-Og gives the following
error:
CC cmdline_parse.o
cmdline_parse.c: In function ‘match_inst’:
cmdline_parse.c:227:5: error: ‘token_p’ may be used uninitialized in
this function [-Werror=maybe-uninitialized]
if (token_p) {
^
This is a false positive, gcc is not able to see that we always go in
the loop at least once, initializing token_p.
Fix the warning by initializing token_p to NULL.
