From b4b73d49958184c833844a3a6f6a3777dd469ceb Mon Sep 17 00:00:00 2001 From: Felix Singer Date: Wed, 14 Oct 2020 18:44:49 +0200 Subject: libpayload/storage/ahci: Use pacc pointer to read device class The PCI bus gets already scanned while gathering system information. Therefore, use the pacc pointer from sysinfo_t to read the device class of PCI devices instead of rescanning the bus.
