[PATCH 0/5] drm/gma500: Managed cleanup

[PATCH 0/5] drm/gma500: Managed cleanup

[Thomas Zimmermann]

Switch gma500 to managed cleanup and remove the manual cleanup
code from the driver's PCI callbacks.

Managed cleanup involves embedding the DRM device structure in the
driver's structure. In preparation, patch 1 replaces references all
references to dev_private with a helper function.

Patch 2 adds managed cleanup for pci_enable_device().

Patches 3 and 4 embed struct drm_device in struct_drm_psb_private. The
structure's memory is being automatically released.

Patch 5 adds managed cleanup for the device resources. Instead of
calling the large, monolithic function psb_driver_unload(), the release
code could be split up split into smaller helpers and reuse exising
functionality from devres.

Future work: for a number of drivers, the PCI remove callback contains
only a single call to drm_device_unregister(). In a later patchset,
this could be implemented as another shared helper within DRM.

Tested on Atom N2800 hardware.

Thomas Zimmermann (5):
  drm/gma500: Replace references to dev_private with helper function
  drm/gma500: Disable PCI device during shutdown
  drm/gma500: Embed struct drm_device in struct drm_psb_private
  drm/gma500: Remove dev_priv branch from unload function
  drm/gma500: Managed device release

[PATCH 1/5] drm/gma500: Replace references to dev_private with helper function

[Thomas Zimmermann]

Replace most references to struct drm_device.dev_private with the new
helper function to_drm_psb_private(). The only references left are in
assignments and the helper itself.

[PATCH 2/5] drm/gma500: Disable PCI device during shutdown

[Thomas Zimmermann]

Use managed disablement of PCI devices via pcim_device_enable().
Disables the PCI device and simplifies error rollback in probe
function.

[PATCH 3/5] drm/gma500: Embed struct drm_device in struct drm_psb_private

[Thomas Zimmermann]

Embed struct drm_device in struct drm_psb_private. Replace the use
of dev_private by an upcast operation. Switch to managed release of
struct drm_psb_private.
