From 97fa1c5ca680bdee2c650e3aadf2a839b92f3f0e Mon Sep 17 00:00:00 2001 From: Himangi Saraogi Date: Tue, 29 Jul 2014 18:12:18 +0200 Subject: cpupower: mperf monitor: Correct use of ! and & In commit ae91d60ba88ef0bdb1b5e9b2363bd52fc45d2af7, a bug was fixed that involved converting !x & y to !(x & y). The code below shows the same pattern, and thus should perhaps be fixed in the same way. The Coccinelle semantic patch that makes this change is as follows: // @@ expression E1,E2; @@ ( !E1 & !E2 | - !E1 & E2 + !(E1 & E2) ) // Signed-off-by: Himangi Saraogi Signed-off-by: Thomas Renninger Signed-off-by: Rafael J.
