Using struct drm_device.pdev is deprecated. Convert bochs to struct drm_device.dev. No functional changes.

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.

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.

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. 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

Add bochs_hw_set_*_endian() helper functions, to set the framebuffer byteorder at mode set time. Support both DRM_FORMAT_XRGB8888 and DRM_FORMAT_BGRX8888 framebuffer formats, no matter what the native machine byte order is.

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:

Call it from bochs_hw_setfb(). This also allows to make bochs_hw_setformat static.
