Another small batch of patches to be seen as preparation for adding
support of the newly available esd CAN-USB/3 to esd_usb.c.
Due to some unresolved questions adding support for
CAN_CTRLMODE_BERR_REPORTING has been postponed to one of the future
patches.
*Resend of the whole series as v3 for easier handling.*
---
* Changelog *
v2 -> v3:
* More specific subjects
* Try to use imperative instead of past tense
v1 -> v2:
* [Patch v2 1/3]: No changes.
* [Patch v2 2/3]: Make use of can_change_state() and relocate testing
alloc_can_err_skb() for NULL to the end of esd_usb_rx_event(), to
have things like can_bus_off(), can_change_state() working even in
out of memory conditions.
* [Patch v2 3/3]: No changes. I will 'declare esd_usb_msg as an union
instead of a struct' in a separate follow-up patch.
