Re: [PATCH 1/4] silicom: checkpatch: assignments in if conditions

This will need to be redone because there were some buggy extra
lines added toward the end of the patch.

This blank line is needed.  (Put a blank line between declarations
and code).

Same for this blank line and all the following instances.

These added lines do not belong.  The patch will need to be redone
to fix this bug.

Please put curly brace {} around multi-line indents.  Even though
they are not needed for semantic reasons they make the code more
readable.
