Subject[PATCH v2 0/6] can: add support for ETAS ES58X CAN USB
The purpose of this patch series is to introduce a new CAN USB
driver to support ETAS USB interfaces (ES58X series).

During development, issues in drivers/net/can/dev.c where discovered,
the fix for those issues are included in this patch series.

We also propose to add two helper functions in include/linux/can/dev.h
which we think can benefit other drivers: get_can_len() and

The driver indirectly relies on
([PATCH] can: raw: add missing error queue support) for the call to
skb_tx_timestamp() to work but can still compile without it.

*Side notes*: scripts/ returns 4 'checks' findings in
[PATCH 5/6]. All those findings are of type: "Macro argument reuse 'x'
possible side-effects?". Those arguments reuse are actually made by
calling either __stringify() or sizeof_field() which are both
pre-processor constant. Furthermore, those macro are never called with
arguments sensible to side-effects. So no actual side effect would

- Fixed -W1 warnings in PATCH 5/6 (v1 was tested with GCC -WExtra
but not with -W1).
- Added lsusb -v information in PATCH 6/6 and rephrased the comment.
- Take care to put everyone in CC of each of the patch of the series
(sorry for the mess in v1...)

can: dev: add a helper function to get the correct length of Classical
can: dev: __can_get_echo_skb(): fix the return length
can: dev: add a helper function to calculate the duration of one bit
can: usb: etas_es58X: add support for ETAS ES58X CAN USB interfaces
usb: cdc-acm: add quirk to blacklist ETAS ES58X devices
