Our CI found this when building with clang (seems to have
the option on by deafult)
iwpan.c:469:13: warning: absolute value function 'abs' given an argument of type 'long' but has parameter of type 'int' which may cause truncation of value [-Wabsolute-value]
cmd_size = abs((long)&__section_set - (long)&__section_get);
^
iwpan.c:469:13: note: use function 'labs' instead
cmd_size = abs((long)&__section_set - (long)&__section_get);
^~~
labs
This also follows a change in iw, where we derived from.
