[PATCH] staging: r8188eu: core: remove goto statement

[Saurav Girepunje]

Remove the goto statement from rtw_do_join(). In this function goto
can be replace by return statement. As on goto label exit, function only
return it is not performing any cleanup. Avoiding goto will improve
the function readability.

You need to read section 14 of Documentation/process/submitting-patches.rst to 
learn how to submit a revised patch. Resubmitting such a revision using the same 
subject line is likely to confuse reviewers and maintainers alike, if not 
patchworks.

Why did I get it twice? At least I got two messages with that subject line.

OK, I will send the other patch to improve this function,
Thanks Dan for review.

I hate pointless "goto exit;" labels, but there isn't a rule against
them and I feel like this is not a good enough patch on its own.  There
is so much other stuff wrong with this function.  It probably *should*
have some error handling for example.

I don't think this patch really adds enough value.  Take a look at the
function and almost every line can be improved...

Remove the goto statement from _rtw_init_recv_priv(). In this function goto
can be replace by return statement. As on goto label exit, function
only return it is not performing any cleanup. Avoiding goto will
