From d93fe31020d138ca5f4fc1c8afce5acb8f724823 Mon Sep 17 00:00:00 2001 From: Mario Six Date: Mon, 29 Apr 2019 01:58:37 +0530 Subject: [PATCH] spi: mpc8xxx: Fix comments There are some comments on the same line as the code they document. Put comments above the code lines they document, so the line length is not unnecessarily increased.
