From 79b09aac000a8cd1facf3ce23958d2a911d88f33 Mon Sep 17 00:00:00 2001 From: Ian Abbott Date: Tue, 27 Jan 2015 18:16:54 +0000 Subject: [PATCH] staging: comedi: comedi_compat32.c: reformat other block comments Use the usual block comment style. Combine some consecutive comments into block comments. Also remove part of a comment referring to `ptr_to_compat()` not being implemented until kernel version 2.6.11 as it's irrelevant.
