Hi Bjorn,
After merging the pci tree, today's linux-next build (powerpc
ppc64_defconfig) failed like this:
arch/powerpc/kernel/pci-common.c: In function 'pcibios_setup
_device':
arch/powerpc/kernel/pci-common.c:406:15: error: 'virq' may be used uninitialized in this function [-Werror=maybe-uninitialized]
pci_dev->irq = virq;
~~~~~~~~~~~~~^~~~~~
arch/powerpc/kernel/pci-common.c:365:15: note: 'virq' was declared here
unsigned int virq;
^~~~
Caused by commit
c5042ac60fe5 ("powerpc/pci: Use of_irq_parse_and_map_pci() helper")
I have applied the following patch for today:
