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.)
