From 1204d12a494cf5dff497859a5febf2ae30a28970 Mon Sep 17 00:00:00 2001 From: Jan Kundrát Date: Tue, 28 Aug 2018 10:07:40 +0200 Subject: i2c: algos: bit: make the error messages grepable MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Yep, I went looking for one of these, and I wasn't able to find it easily. That's worse than a line which is 82-chars long, IMHO.
