Hello Jakub, hello David,

this is a pull request of 3 patches for net/master.

All three patches are by Vincent Mailhol and fix a potential use after free bug
in the CAN device infrastructure, the vxcan driver, and the peak_usk driver. In
the TX-path the skb is used to read from after it was passed to the networking
stack with netif_rx_ni().

Note: Patch 1/3 touches "drivers/net/can/dev.c". In net-next/master this file
has been moved to drivers/net/can/dev/dev.c [1] and parts of it have been
transfered into separate files. This may result in a merge conflict. Please
carry this patch forward, the change is rather simple. Drop us a note if
needed. Are any actions needed with regards to linux-next?

[1] 3e77f70e7345 can: dev: move driver related infrastructure into separate subdir

regards,
Marc
