batman-adv: count_real_packets() in batman-adv assumes char is signed
count_real_packets() in batman-adv assumes char is signed, and returns -1 through it: net/batman-adv/routing.c: In function 'receive_bat_packet': net/batman-adv/routing.c:739: warning: comparison is always false due to limited range of data type Use int instead. Signed-off-by: David Howells <dhowells@redhat.com> [sven@narfation.org: Rebase on top of current version] Signed-off-by: Sven Eckelmann <sven@narfation.org>
