This series contains some cleanups for the hns driver:
- patch 1 unifies format of prints in hns_roce_hw_v2.c and hns_roce_pd.c.
- patch 2 ~ 5 are some simple modifications.
- patch 6 ~ 10 remove some dead codes.
Previous discussions can be found at:
https://patchwork.kernel.org/cover/11447213/
Changes since v1:
- Drop patch 3/11 from series v1 because it's wrong to use IS_ERR_OR_NULL
on a pointer returned by kmalloc().

Use ibdev_err/dbg/warn() instead of dev_err/dbg/warn(), and modify some
prints into format of "failed to do something, ret = n".

ceq and aeq is a ring buffer, consumer index of them will be set to zero
after reaching the maximum value. The warning should be removed or it may
mislead the users.

The field smac in ib_wc was used for create AH and then it will be treated
as destination mac address in UD sqwqe, but related code about filling smac
into AH has been removed in core. Actually, the dmac in UD sqwqe is parsed
from the dgid in grh which is passed in by ULP now, so this assignment
should be removed.

Type of qp has been checked in check_send_valid(), so this judgment should
be removed.

It is unfortunate these have to remain as dev_err()
I've thought about setting the name during ib_alloc_dev, which would
avoid this, what do you think?

Hi Jason,
Thanks for your comments. I agree with you and make a simple test by just
moving assign_name() into _ib_alloc_device(), and ibdev_*() works fine
anywhere in hns. But I'm not sure if there are any side effects.
I noticed that the code about name assignment is implemented by you, could
you please explain why put assign_name() in ib_register_device() rather than
ib_alloc_device()?
Thanks
Weihang

Hmm. It actually looks like it should work now, older versions may
have had problems, but this looks OK.
