From 99c14e4df6144bca12dcac657266a7b8216aaa16 Mon Sep 17 00:00:00 2001 From: Rasmus Villemoes Date: Fri, 20 Feb 2015 14:47:30 +0100 Subject: [PATCH] rtc: mc13xxx: fix obfuscated and wrong format string According to C99, %2.s means 'print two spaces' (a precision of . without following digits or * means 0). The kernel's printf implementation, however, treats that case as if no precision was given, but relying on that quirk is rather silly. Also, since no - (aka left-justify) flag is given, the field with of 2 would then cause the alarm->enabled case to come out as "o n". Deobfuscate it.
