Since 'commit fc8d0590d914 ("libcxgbi: Add ipv6 api to driver")' was introduced, there is no call to csk_print_port() and csk_print_ip() is made. Hence kernel build with clang complains below message: drivers/scsi/cxgbi/libcxgbi.c:2287:19: warning: unused function 'csk_print_port' [-Wunused-function] static inline int csk_print_port(struct cxgbi_sock *csk, char *buf) ^ drivers/scsi/cxgbi/libcxgbi.c:2298:19: warning: unused function 'csk_print_ip' [-Wunused-function] static inline int csk_print_ip(struct cxgbi_sock *csk, char *buf) ^ So it had better remove csk_print_port() and csk_print_ip() to stop warning.
