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. Miller <davem@davemloft.net>
