Subject: [PATCH 1/2] iwpan: fix clang compiler warning on absolute-value
Date: Thu,  6 Dec 2018 21:26:01 +0100	[thread overview]
Message-ID: <20181206202602.22176-1-stefan@datenfreihafen.org> (raw)

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.
