[PATCH v1 12/12] PCI: Simplify sysfs ROM cleanup

From: Bjorn Helgaas
Date: Thu Mar 03 2016 - 11:55:40 EST


The value of pdev->rom_attr is the definitive indicator of the fact that
we're created a sysfs attribute. Check that rather than rom_size, which is
only used incidentally when deciding whether to create a sysfs attribute.
