From: Robert Richter Date: Tue, 21 Sep 2010 16:09:00 +0000 (+0200) Subject: oprofile, x86: Remove duplicate check for IBS_CAPS_OPCNT X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=fc889aa23f4767c1c3f77fce11e17bb0a638971f;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git oprofile, x86: Remove duplicate check for IBS_CAPS_OPCNT Since oprofile is setting up ibs_op/dispatched_ops in the fs only if the feature is available, its corresponding variable ibs_config.dispatched_ops is only set, if the feature is available. Thus the check is duplicate and can be removed.
