[PATCH] PCI: rcar: Use common error handling code in rcar_pcie_enable_msi()

[SF Markus Elfring]

From: Markus Elfring <elfring@users.sourceforge.net>
Date: Mon, 30 Oct 2017 08:28:06 +0100

Adjust a jump target so that a specific error message is stored only once
at the end of this function implementation.
Replace two calls of the function "dev_err" by goto statements.

This issue was detected by using the Coccinelle software.

This is fine by me except that the change in the name of the goto label
seems spurious. If think it should be left as-is. But if you really want to
change it then as it is an error path I should suggest it describe that its
an error and what unwinding is done, f.e.  err_remove_domain.

Thanks for another bit of change acceptance.

I am curious if the popularity of a jump label like “err” will decrease
(in the Linux source files) over time.

* Do you get such a kind of information only when the prefix “err_”
  is added to this identifier?

* Do you prefer to stress the “domain removal”
  (or the shown error message) in the label?

Markus

If your current patch bombing is successful then it will, at least in the
short term. But my comments relate to the current best practice,
not the one you seem to be trying to introduce.

Yes, err indicates its an error path.

I prefer to stress the unwind path as that is the most important
aspect of the error path.


I have no interest in a prelonged debate about the naming of labels.
As I pointed out its a spurious aspect of your change. If you wish me to
Ack your change then please either drop that change or update it - as I
already suggested. Else lets discontinue this sub-thread.

Moving the error message is confusing and counter-productive:
if you need to add another error case + goto err_remove_domain
later, you'll have to move it back to all the older cases.

Moving the error message is confusing and counter-productive:
if you need to add another error case + goto err_remove_domain
later, you'll have to move it back to all the older cases.
