Subject: [PATCH 1/2] 8139too: clean up spaces and TABs
From: Márton Németh <nm127@...email.hu>
Clean up the following errors and warnings reported by checkpatch.pl:
- space prohibited between function name and open parenthesis '('
- space required before the open brace '{'
- code indent should use tabs where possible
- line over 80 characters
- spaces required around that '=' (ctx:VxW)
