From 9a1a1f404be55b07aea64864f98d7306cc493360 Mon Sep 17 00:00:00 2001 From: Tai Nguyen Date: Thu, 13 Oct 2016 11:09:16 -0700 Subject: perf: xgene: Remove bogus IS_ERR() check In acpi_get_pmu_hw_inf we pass the address of a local variable to IS_ERR(), which doesn't make sense, as the pointer must be a real, valid pointer. This doesn't cause a functional problem, as IS_ERR() will evaluate as false, but the check is bogus and causes static checkers to complain. Remove the bogus check.
