Series drm: Move struct drm_device.pdev to legacy | expand

Commit Message

Thomas Zimmermann Jan. 18, 2021, 1:14 p.m. UTC 
We have DRM drivers based on USB, SPI and platform devices. All of them
are fine with storing their device reference in struct drm_device.dev.
PCI devices should be no exception. Therefore struct drm_device.pdev is
deprecated.

Instead upcast from struct drm_device.dev with to_pci_dev(). PCI-specific
code can use dev_is_pci() to test for a PCI device. This patch changes
the DRM core code and documentation accordingly.

v4:
	* split-off pdev deprecation into separate patch
