Subject: [PATCH net-next v2 00/11] devlink: retain error in struct devlink_fmsg
Date: Tue, 17 Oct 2023 12:53:30 +0200	[thread overview]
Message-ID: <20231017105341.415466-1-przemyslaw.kitszel@intel.com> (raw)

Extend devlink fmsg to retain error (patch 1),
so drivers could omit error checks after devlink_fmsg_*() (patches 2-10),
and finally enforce future uses to follow this practice by change to
return void (patch 11)

Note that it was compile tested only.

bloat-o-meter for whole series:
add/remove: 8/18 grow/shrink: 23/40 up/down: 2017/-5833 (-3816)

changelog:
v2: extend series by two more drivers (qed, qlge);
    add final cleanup patch, since now whole series should be merged in
    one part (thanks Jiri for encouragement here);

v1:
