[PATCH] PCI: Remove unnecessary of_irq.h includes

[PATCH] PCI: Remove unnecessary of_irq.h includes

[Bjorn Helgaas]

From: Bjorn Helgaas <bhelgaas@google.com>

Many host controller drivers #include <linux/of_irq.h> even though they
don't need it.  Remove the unnecessary #includes.

[+cc Pali, heads-up for trivial addition of <linux/irqdomain.h> to

No problem!

I think what happened is the pcie-microchip-host.c uses
irq_domain_add_linear() so it needs <linux/irqdomain.h>, but it
currently gets it via <linux/of_irq.h>, which it doesn't otherwise
need.

I added a preparatory patch to include <linux/irqdomain.h> explicitly,
but I haven't been able to cross-build either riscv or ia64 to verify
this fix.  I'll wait a few days and post an updated series for the
0-day bot to test.

Same situation for pcie-altera-msi.c.

pci-mvebu.c also relies on getting <linux/irqdomain.h> via
<linux/of_irq.h>, but it actually depends on of_irq.h, so I'll just
add an irqdomain.h include there.

Bjorn

I saw you saying you couldn't find the config from LKP, FWIW a build
using riscv defconfig w/ CONFIG_PCIE_MICROCHIP_HOST=y fails for me
in the same way as lkp reports.
Otherwise, dump the patch in response to this and I'll give it a shot
later if you like?

HTH,
Conor.

Sorry, my fault, "config" was a MIME attachment.  Possibly update the
instructions:

  - # save the config file
  + # save the config file from the MIME attachment

Hi Bjorn,

You may need to install the below package, or similar package for other OS:

$ dpkg -S /usr/bin/s390x-linux-gnu-ld
binutils-s390x-linux-gnu: /usr/bin/s390x-linux-gnu-ld

 >>          # install s390 cross compiling tool for clang build
 >>          # apt-get install binutils-s390x-linux-gnu

Best Regards,
Rong Chen
