[PATCH 08/17] coresight: Drop double check for ACPI companion device

[Mathieu Poirier]

From: Andy Shevchenko <andriy.shevchenko at linux.intel.com>

acpi_dev_get_resources() does perform the NULL pointer check against
ACPI companion device which is given as function parameter. Thus,
there is no need to duplicate this check in the caller.
