can: ucan: remove set but not used variable 'udev'

[ Upstream commit 207681fc5f3d5d398f106d1ae0080fc2373f707a ] Fixes gcc '-Wunused-but-set-variable' warning: drivers/net/can/usb/ucan.c: In function 'ucan_disconnect': drivers/net/can/usb/ucan.c:1578:21: warning: variable 'udev' set but not used [-Wunused-but-set-variable] struct usb_device *udev; Signed-off-by: YueHaibing Reviewed-by: Martin Elshuber Signed-off-by: Marc Kleine-Budde Signed-off-by: Sasha Levin

can: kvaser_usb: Fix potential uninitialized variable use

2018-11-27T15:13:09+00:00

commit 95217260649aa504eb5d4a0d50959ca4e67c8f96 upstream. If alloc_can_err_skb() fails, cf is never initialized. Move assignment of cf inside check. Reported-by: Dan Carpenter Signed-off-by: Jimmy Assarsson Cc: linux-stable Signed-off-by: Marc Kleine-Budde Signed-off-by: Greg Kroah-Hartman

can: kvaser_usb: Fix accessing freed memory in kvaser_usb_start_xmit()

2018-11-27T15:13:09+00:00

commit e13fb9b37cc00616b90df2d620f30345b5ada6ff upstream. The call to can_put_echo_skb() may result in the skb being freed. The skb is later used in the call to dev->ops->dev_frame_to_cmd(). This is avoided by moving the call to can_put_echo_skb() after dev->ops->dev_frame_to_cmd().

The BTF conflicts were simple overlapping changes. The virtio_net conflict was an overlap of a fix of statistics counter, happening alongisde a move over to a bonafide statistics structure rather than counting value on the stack. Signed-off-by: David S. Miller

can: kvaser_usb: Add support for Kvaser USB hydra family

2018-07-27T08:40:19+00:00

This patch adds support for a new Kvaser USB family, denoted hydra. The hydra family currently contains USB devices with one CAN channel up to five. There are devices with and without CAN FD support.

can: kvaser_usb: Split driver into kvaser_usb_core.c and kvaser_usb_leaf.c

2018-07-27T08:40:19+00:00

First part of adding support for Kvaser USB device family "hydra". Split kvaser_usb.c into kvaser_usb/kvaser_usb{.h,_core.c,_leaf.c}. kvaser_usb_core.c contains common functionality, such as USB writing/reading and allocation of netdev. kvaser_usb_leaf.c contains device specific code, used in kvaser_usb_core.c. struct kvaser_usb_dev_ops contains device specific functions that are common for all devices in the family. While, struct kvaser_usb_dev_cfg describes the device configurations in terms of CAN clock frequency, timestamp frequency and CAN controller bittiming constants.
