[PATCH] staging: rtl8723bs: fix unnecessary else block with only a break statement

Warning found by checkpatch.pl : else is not generally useful after a
break or return. The function would reach the break statement after
if-elseif block even if the else block is not used.

No I didn't test the code. And I don't have the required hardware. But I would like to know what are widely used test methods in linux kernel dev to test a driver when you don't have the relevant hardware vs when you have one for and finally test the code. At first it seemed a trivial change to me because that else block would only execute if the if-elseif block didnt execute, which made me come to the decision that the else block was unnecessary.

Please wrap your lines :)

Look at the logic of what you just changed here, is it identical to what
was present before your change?  If not, what is different?  checkpatch
is for coding style issues, not logic changes, right?

See the mailing list archives for many discussions about this type of
"cleanup".
