Subject: [PATCH v4 0/4] can: add support for ETAS ES58X CAN USB
Date: Sat, 17 Oct 2020 02:13:29 +0900 [thread overview]
Message-ID: <20201016171402.229001-1-mailhol.vincent@wanadoo.fr> (raw)
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 were discovered,
the fix for those issues are included in this patch series.
We also propose to add one helper functions in include/linux/can/dev.h
which we think can benefit other drivers: get_can_len().
*Side notes*: scripts/checkpatch.pl returns 4 'checks' findings in
[PATCH 4/4]. 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.
Changes in v4:
- Remove from the series the patches with have already been merged
into net-next.
Reference: https://lkml.org/lkml/2020/10/4/78
Reference: https://lkml.org/lkml/2020/10/5/355
- Modify [PATCH 4/4] according to comments from Marc.
Reference: https://lkml.org/lkml/2020/10/4/80)
Changes in v3:
- Added one additional patch: [PATCH v3 2/7] can: dev: fix type of
get_can_dlc() and get_canfd_dlc() macros.
- Make get_can_len() return u8 and make the skb const in PATCH 3/7.
- Remove all the calls to likely() and unlikely() in PATCH 6/7.
Changes in v2:
- Fixed -W1 warnings in PATCH 6/7 (v1 was tested with GCC -WExtra
but not with -W1).
- Added lsusb -v information in PATCH 7/7 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...)
