similar to: [PATCH v3] drm/cirrus: add drm_driver.release callback.

Move final cleanups from cirrus_pci_remove() to the new callback. Add drm_atomic_helper_shutdown() call to cirrus_pci_remove(). Use drm_dev_{enter,exit,unplug} to avoid touching hardware after device removal. v4: add changelog. v3: use drm_dev*. v2: stop touching hardware after pci_remove().

Move final cleanups from cirrus_pci_remove() to the new callback. Add drm_atomic_helper_shutdown() call to cirrus_pci_remove(). Set pointers to NULL after iounmap() and check them before using them to make sure we don't touch released hardware.

Time to kill some bad sample code people are copying from ;) This is a complete rewrite of the cirrus driver. The cirrus_mode_set() function is pretty much the only function which is carried over largely unmodified. Everything else is upside down. It is a single monster patch. But given that it does some pretty fundamental changes to the drivers workflow and also reduces the code size by

Update the cirrus driver to follow current best practices. While the driver's hardware is obsolete, the cirrus driver is still one of the go-to modules to learn about writing a DRM driver. So keep it in good shape. Patches 1 to 3 simplify blitting and convert it to the DRM's current helpers. Patches 4 to 8 replace simple-KMS helpers with DRM's regular atomic helpers. The former are

Upcasting using a container_of macro is more typesafe, faster and easier for the compiler to optimize.
