Subject: [PATCH v1 1/7] PCI: Introduce pci_bus_*() printing macros when device is not available
Date: Mon,  8 Mar 2021 14:20:14 +0200
Message-ID: <20210308122020.57071-2-andriy.shevchenko@linux.intel.com> (raw)
In-Reply-To: <20210308122020.57071-1-andriy.shevchenko@linux.intel.com>

In some cases PCI device structure is not available and we want to print
information based on the bus and devfn parameters. For this cases introduce
pci_bus_*() printing macros and replace in existing users.
