2017-08-16drm/exynos: Use .dumb_map_offset and .dumb_destroy defaultsNoralf Trønnes3-35/+2
This driver can use the drm_driver.dumb_destroy and drm_driver.dumb_map_offset defaults, so no need to set them. Use drm_gem_dumb_map_offset() in exynos_drm_gem_map_ioctl() and remove exynos_drm_gem_dumb_map_offset().

2017-08-11drm: Only lastclose on unload for legacy driversDaniel Vetter1-1/+2
The only thing modern drivers are supposed to do in lastclose is restore the fb emulation state. Which is entirely optional, and there's really no reason to do that. So restrict it to legacy drivers (where the driver cleanup essentially happens in lastclose). This will also allow us to share the unregister function with drm_dev_unplug().

So I think there's 3 cases: - Trying to unload the module. You can't do that while anyone has the fd still open, so lastclose is guaranteeed to run. - Forcefully unbinding the driver through sysfs. Not any better, since the can_switch stuff checks for the open count, and so will delay the delayed switch no matter what. - Actual hotremoval: a) not implemented since none of the drivers taking part in vgaswitcheroo correctly unplug the drm device and b) you can't hotremove a chip from a laptop. v2: Extend commit message with m-l discussion.

This is useful to allow GL to provide defined results for overlapping glBlitFramebuffer, which X11 in turn uses to accelerate uncomposited window movement without first blitting to a temporary. x11perf -copywinwin100 goes from 1850/sec to 4850/sec. v2: Default to the same behavior as before when the flags aren't passed.
