ACPI: remove superfluous NULL pointer check from acpi_processor_get_throttling_info()
Dan's list contains: drivers/acpi/processor_throttling.c +1139 acpi_processor_get_throttling_info(11) warning: variable derefenced before check 'pr' acpi_processor_get_throttling_info() is never called with pr == NULL. [ bart: the potential NULL pointer dereference was finally fixed in (much later than mine) commit 5cfa245 but my patch is still valid ] Reported-by: Dan Carpenter <error27@gmail.com> Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Len Brown <len.brown@intel.com>
