    Subject[PATCH 0/6] can: add support for ETAS ES58X CAN USB
    Date
    Resending: In my previous e-mail, I forgot to include the
    linux-kernel@vger.kernel.org in the cover letter which broke the chain
    reply... Sorry for the spam.

    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
    can_bit_time().

    The driver indirectly relies on https://lkml.org/lkml/2020/9/26/251
    ([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/checkpatch.pl 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
    occur.

    Thank you for your comments.

    context
