Cheers, Will --->8 >From 21fa771c94c4359807bb92dc8532b25c323ac543 Mon Sep 17 00:00:00 2001 From: Chen Gang Date: Sat, 16 Feb 2013 06:49:49 +0000 Subject: [PATCH] ARM: perf: remove erroneous semicolon from event initialisation Commit 9dcbf466559f ("ARM: perf: simplify __hw_perf_event_init err handling") tidied up the error handling code for perf event initialisation on ARM, but a copy-and-paste error left a dangling semicolon at the end of an if statement. This patch removes the broken semicolon, restoring the old group validation semantics.
