description:
You wrote what you did in the description. Even when the why can be
likely answered as well it is not sufficient for Greg K-H.

I propose something like:
Combine two nested if statements into a single one to increase readability.

Or

Combine two nested if statements into a single one to shorten code.

subject:
I am guessing. The subject could may be remain but I think it is to
general. Please consider that we can have multiple of this subjects what
is not good. How to know which patch is which?

I propose something like:
staging: r8188eu: combine nested if statements in function xxxx

Or

staging: r8188eu: combine nested if statements in file xxxx


But consider that the patches that were accepted do also have a not so
specific subject. The description was very clear about the "why". There
the reason was always checkpatch.

Bye Philipp
