[PATCH v3 0/2] prevent incoherent can configuration in case of early return in the CAN netlink interface

[Vincent Mailhol <mailhol.vincent@wanadoo.fr>]

This series of two patch prevents, once for all, can_priv to be in an
inconsistent state in case of an early return in can_changelink() due
to invalid parameters.

* Changelog *

v2 -> v3:
  - Allocate the temporary struct can_priv on the heap instead of
    declaring it as static.
  - Split the patch into two to make it easier to backport to LTS
    kernels and add the "Fixes" tag.

v1 -> v2:
  - Change the prototype of can_calc_tdco() so that the changes are
    applied to the temporary priv instead of netdev_priv(dev).

Vincent Mailhol (2):
  can: netlink: prevent incoherent can configuration in case of early
    return
  can: bittiming: change can_calc_tdco()'s prototype to not directly
    modify priv
