net/caif: Use pr_fmt 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>

caif: Bugfix for socket priority, bindtodev and dbg channel. Changes: o Bugfix: SO_PRIORITY for SOL_SOCKET could not be handled in caif's setsockopt, using the struct sock attribute priority instead. o Bugfix: SO_BINDTODEVICE for SOL_SOCKET could not be handled in caif's setsockopt, using the struct sock attribute ifindex instead. o Wrong assert statement for RFM layer segmentation. o CAIF Debug channels was not working over SPI, caif_payload_info containing padding info must be initialized. o Check on pointer before dereferencing when unregister dev in caif_dev.c Signed-off-by: Sjur Braendeland <sjur.brandeland@stericsson.com> Signed-off-by: David S.
