Subject: USB: c67x00-ll-hpi.c: signedness bug in ll_recv_msg()
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=a29c408521b2b8969fead6aa3c7819800d6b473a;p=openwrt%2Fstaging%2Fblogic.git

USB: c67x00-ll-hpi.c: signedness bug in ll_recv_msg()

The callers expect this function to return zero on success or -EIO if it
times out.  The type should be int instead of unsigned short.
