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. The bug is reported by Dan Carpenter <dan.carpenter@oracle.com> in [1] [1] https://www.spinics.net/lists/arm-kernel/msg535957.html Signed-off-by: Tai Nguyen <ttnguyen@apm.com> Acked-by: Mark Rutland <mark.rutland@arm.com> Signed-off-by: Will Deacon <will.deacon@arm.com>
