Message-Id: <1322820073-19347-3-git-send-email-xi.wang@gmail.com> The error handling with (ret < 0) didn't work where ret is a u32. Use int instead. To be consistent we also change the functions to return an int. Signed-off-by: Xi Wang <xi.wang@gmail.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
