[PATCH 0/2] rtl8723bs: clean up error handling

[Omer El Idrissi]

This series cleans up error handling for function sdio_init()
and sdio_dvobj_init() by using conventional errno instead of
vendor-defined _SUCCESS/_FAIL macros when returning

You're going to need to start labeling your patches as v2 etc.

This patch isn't wrong, per se, but I'd really like for you to update
the callers as well like how you did in the earlier patch.  Right now,
they're still testing for _SUCCESS.

Make sdio_dvobj_init() propagate the error code back instead of -1.

Change rtw_resume_process_normal() to:

	ret = sdio_init();
	if (ret)
		goto whatever_and_return_NULL;

It will make the commit message a little bit more complicated.

    Make sdio_init() propagate standard kernel error codes instead
    of returning _SUCCESS/_FAIL.  There are two callers for this
    function.  sdio_dvobj_init() already returns negative values
    but the caller doesn't check for errors so changing this doesn't
    affect anything.  rtw_resume_process_normal() returns NULL on
    error so leave that as-is.

Sorry, for being a bit nit-picky on this but you might end up potentially
sending a lot of these patches.

Re: [PATCH 2/2] staging: rtl8723bs: cleanup return in sdio_init()

[Omer]

I will make a v2 patch for this series.
My question is do I go back to returning error pointers for
sdio_dvobj_init? I did that in my original commit so that
the proper errno would be propagated back to the rtw_drv_init probe
function in sdio_intf.c.
sdio_dvobj_init function can fail due to both allocation issues and
sdio_init failure. So i thought it would be more
descriptive to propagate an error pointer instead of NULL for both cases.

Best,
Omer El Idrissi

No, just keep it as return NULL.  But the check should be:

	ret = sdio_init(dvobj);
	if (ret) {

Because that's the standard way to do error handling.  It's slightly
more readable than the alternatives like:

	if (sdio_init(dvobj) < 0) {

It's more descriptive but returning NULL is fine.  Every change
you make adds places where people can disagree with you.  We
want to change from _SUCCESS/_FAIL to standard error codes.  Fine
everyone agrees with that.  But then changing to error pointers?
Some people might agree and some might not.  And then it's like,
okay we have 99 functions which return NULL and 1 function which
returns error pointers.  And we get into a whole discussion about
it.  Forget it.  Just return NULL.

Re: [PATCH v3 0/4] clean up error handling

Sorry, I'm going to ask that you send these one last time. It should
just be 2 patches.  patch 1 stays the same, and patches 2, 3 and 4 get
squashed into the same patch.

The thing is that right now we're changing sdio_init() and then
cleaning up the callers.  We should change it and clean up the callers
all in one go.  One thing per patch means "One complete thing" not
"half a thing per patch".  It makes it easier to review when it's done
in one go, because otherwise, when I'm reviewing patch 2, I have to
check all the callers anyway.

You sent v3 twice, was that on purpose?

[Omer]

Nope.
The signed-off-by tag was off by one letter. so i fixed that and resent it.

Please do not top-post :(

Then that would be a new version, not the same version twice, otherwise
how would we know which to pick?

Please remember, some of us get 1000+ emails a day to deal with, and
when reviewing patches for a subsystem, have to handle hundreds of them
at the same time.  Think about what you would want the messages to look
like if you were on the recieving end.

As a bit of help, why not take some time to review other patches on the
staging list to reduce the overall load and to get more familiar with
how the process works?

thanks,

[PATCH v3 0/4] clean up error handling

[Omer El Idrissi]

This series lets sdio_init() propagate standard kernel error codes 
instead of returning _SUCCESS/_FAIL.  There are two callers for this
function.  rtw_resume_process_normal() already returns negative values 
but the caller doesn't check for errors so changing this doesn't
affect anything.  sdio_dvobj_init() returns NULL on
error so leave that as-is.

v3:
- Add one commit that lets sdio_dvobj_init() use more readable error
  handling
- Add v3 and v2 tags

v2:
- Add one commit that lets rtw_resume_process_normal cleanly check
  errors and return errno instead of using vendor-defined slop

v1:
- Use direct returns in sdio_dvobj_init()
- Cleanup return in sdio_init()
