Hi,

There are lot of clean-up patches floating around at this time.
And I'm unsure if you are both on the same team or not, but in
any case it would be nice if there was some co-ordination.
Because here we have two different versions of the same patch.
Which, from a maintainer and reviewer pov is awkward.

In principle the change(s) look(s) fine to me. But there are some minor
problems.

1. For the patch above, it should be explicitly targeted at net-next.
   (Or net if it was a bug fix, which it is not.)

   Not a huge problem, as this is the default. But please keep this in mind
   for future posts.

	Subject: [PATCH vX net-next]: ...

2. For the patch above, the {} should be dropped, as in the patch below.

3. For both patches. The dev_err_cast_probe should be line wrapped,
   and the indentation should align with the opening (.

		return dev_err_cast_probe(dev, clk,
					  "error getting core clock\n");

I'd like to ask you to please negotiate amongst yourselves and
post _just one_ v2 which addresses the minor problems highlighted above.

Thanks!

This looks to me like a simple replacement with equivalent code.

I just noticed this (looking at the patch from Hongbo Li).

Thank you Simon, you are correct and I appreciate your proposed
solution.  I'll await a followup patch (perhaps jointly signed
off?)

I apologize for causing confusion, and I will strive to submit patches 
that are truly valuable in the future.
