Subject: [PATCH] cmdline: fix compilation with -Og
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
[ upstream commit 1123f16eb37b19dcabe2b2313f99911c59df91f3 ]
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.
