That applies to both patches.

b4 doesn't pick this ack up for both patches, you either need to do it
on the 0/X message, or on each one individually.

Hi Alaa,

I see you already picked up an ACK on this!

I'm going to comment on the format since I'm aware this is your
first patchset! The grouping is good - 2 cleanups in same file.
Please search in the tutorial for further info on how to present these
as a patchset. You can also peruse the outreachy list for formats of
patchsets as well. I'd expect to see a cover letter.

The other thing I noticed was this: 
>> [PATCH 1/2] staging: r8188eu: add space around arithmatic sign
>> [PATCH 2/2] staging: r8188eu: Add line after declarations
to which I was going to say - 'Well which is the actual preference
for this file or driver: 'add' or 'Add', ie. uppercase or lowercase?  

Looking at the history, it's mixed. So, I guess I'll just suggest
you don't mix it within a patchset.  If a maintainer cares, and try
to set a pattern for the file or driver..

spelling fixup please:
s/arithmatic/arithmetic

and perhpas this would be clearer:
s/sign/operator   (They are arithmetic operators, not signs.)

Alison
