From d39ec6ce34f130d582880d1f3cbe2b38e723cafe Mon Sep 17 00:00:00 2001 From: Paul Mundt Date: Thu, 24 Nov 2011 19:36:46 +0900 Subject: serial: sh-sci: Clarify enable_ms/break_ctl comments. Technically there's nothing we can do for either of these, so update the comments to reflect this, rather than infering that there's additional work to be done.
