From 082e12a05cf317acec2feaf3a78de3f3372feeb3 Mon Sep 17 00:00:00 2001 From: Hanjun Guo Date: Mon, 2 Sep 2013 11:57:38 +0800 Subject: ACPI / processor: remove unnecessary if (!pr) check acpi_processor_errata() is only called in acpi_processor_get_info(), and the argument 'pr' passed to acpi_processor_errata() will never be NULL, so the if (!pr) check is unnecessary and can be removed. Since the 'pr' argument is not used by acpi_processor_errata() any more, so change the argument into void too. Signed-off-by: Hanjun Guo Signed-off-by: Rafael J.
