Subject: [PATCHv2 1/3] silicom: fix whitespace issues in bypass.c
This patch addresses several problems in bypass.c found by checkpatch.
Furthermore it removes/adds some empty lines to make the code more readable.
The following problems are fixed:
- line over 80 characters
- space after logical operator !
- spaces instead of tabs
- missing empty line after local declarations
- empty line after {
The empty line issues were not discovered by checkpatch but in my opinion these
changes make perfect sense in terms of readability.
