[PATCH 0/3] staging: rtl8192e: some refactoring

[Michael Straube]

This series refactors two for loops in _rtl92e_dm_rx_path_sel_byrssi()
to reduce indentation and improve readability.

Compile-tested only, due to lack of hardware.

Michael Straube (3):
  staging: rtl8192e: reduce indentation level
  staging: rtl8192e: remove unnecessary line breaks
  staging: rtl8192e: remove dead code

[PATCH 1/3] staging: rtl8192e: reduce indentation level

[Michael Straube]

Reduce indentation level in _rtl92e_dm_rx_path_sel_byrssi() by negating
if statements and use continue in for loops. This way the indentation
level of the code that is covered by the if checks can be reduced. This
improves readability and clears two checkpatch warnings.

WARNING: Too many leading tabs - consider code refactoring

I would be careful with these changes. These else-if do prevent the
execution of the other else-if, so the code do not behave the same anymore.

The only case this patch doesn't change anything functionally is when the
condition of the removed if-else is mutually exclusive with the conditions
of the following if-else. Are you sure this is the case?

Best regards,
Nam

Ah yes, I had not thought about that. Thanks for pointing out.
I'll have a closer look and resend the series. Either without this patch
or, if it's safe to remove, state it in the commit message.

This patch doesn't affect behavior at all, but to me the original
author wrote the do nothing case for readability, and I don't have a
problem with that.  In fact, I applaud the author for caring about
readability at all which is not a given in staging code.  :P

Then I think it's better to leave it as is. :)
Should I send a v2 with this patched removed or will Greg just apply
the first two patches and ignore this one?

thanks,
