Much better, but you forgot the the Signed-off-by so we can't apply it.

Also it's nice to be more specific with the subject.
[PATCH] Staging: rtl8188eu: rtw_security: tidy up crc32_init().
And for the full commit message maybe write something like:

This code generates a checkpatch warning:

    WARNING: else is not generally useful after a break or return

If we move the declarations to the start of the function then we can
pull the code back one tab and it makes the function a lot more readable.
