Subject: Re: [PATCH] staging: r8188eu: Fix different base types in
 assignments and parameters

1) I'm pretty sure after a little more review that the patch introduces
   bugs.  The data is supposed to be big endian.

2) The commit message did not clearly describe the "bug" and how the it
   looks like to the user.

3) The way we set variables to zero is we say "foo = 0;"  We do not
   say "foo ^= foo;".  Everyone knows the XOR a variable with itself
   trick but obfuscated code makes us cross.

4) The unions were unnecessary and ugly/bad.
