[Intel-gfx] [PATCH] drm/i915: Fix implicit use of struct pci_dev

[broonie at kernel.org]

From: Mark Brown <broonie at kernel.org>

intel_device_info.h references struct pci_dev but does not ensure that
the struct has been declared, causing build failures if something in
other headers changes so that the implicit dependency it is relying on
is no longer satisfied:

In file included from /tmp/next/build/drivers/gpu/drm/i915/intel_device_info.h:32,
                 from /tmp/next/build/drivers/gpu/drm/i915/gt/uc/intel_uc_fw.h:11,
                 from /tmp/next/build/drivers/gpu/drm/i915/gt/uc/intel_uc_fw.c:11:
/tmp/next/build/drivers/gpu/drm/i915/display/intel_display.h:643:39: error: 'struct pci_dev' declared inside parameter list will not be visible outside of this definition or declaration [-Werror]
  643 | bool intel_modeset_probe_defer(struct pci_dev *pdev);
      |                                       ^~~~~~~
cc1: all warnings being treated as errors

Add a declaration of the struct to fix this.
