similar to: [PATCH 28/51] drm/bochs: Drop explicit drm_mode_config_cleanup

Instead rely on the automatic clean, for which we just need to check that drm_mode_config_init succeeded. To avoid an inversion in the cleanup we also have to move the dev_private allocation over to drmm_kzalloc.

Call drm_dev_unregister() first in bochs_pci_remove(). Hook bochs_unload() into the new .release callback, to make sure cleanup is done when all users are gone. Add ready bool to state struct and move bochs_hw_fini() call from bochs_unload() to bochs_pci_remove() to make sure hardware is not touched after bochs_pci_remove returns.

We can even delete the drm_driver.release hook now! This is made possible by a preceeding patch which added a drmm_ cleanup action to drm_mode_config_init(), hence all we need to do to ensure that drm_mode_config_cleanup() is run on final drm_device cleanup is check the new error code for _init(). v2: Explain why this cleanup is possible (Laurent). v3: Use drmm_mode_config_init() for more

Hi Peter, Thank you for the patch! Perhaps something to improve: [auto build test WARNING on linus/master] [also build test WARNING on v4.19-rc2 next-20180906] [if your patch is applied to the wrong git tree, please drop us a note to help improve the system] url: https://github.com/0day-ci/linux/commits/Peter-Wu/bochs-convert-to-drm_fb_helper_fbdev_setup-teardown/20180907-154819 config:

The data structure |struct drm_vram_mm| and its helpers replace bochs' TTM-based memory manager. It's the same implementation; except for the type names. v4: * don't select DRM_TTM or DRM_VRAM_MM_HELPER v3: * use drm_gem_vram_mm_funcs * convert driver to drm_device-based instance v2: * implement bochs_mmap() with drm_vram_mm_mmap() Signed-off-by: Thomas Zimmermann <tzimmermann
