This patch standardizes caif message logging prefixes. Add #define pr_fmt(fmt) KBUILD_MODNAME ":%s(): " fmt, __func__ Add missing "\n"s to some logging messages Convert pr_warning to pr_warn This changes the logging message prefix from CAIF: to caif: for all uses but caif_socket.c and chnl_net.c. Those now use their filename without extension. Signed-off-by: Joe Perches <joe@perches.com> Signed-off-by: David S. Miller <davem@davemloft.net>
