[PATCH v2 0/1] Stop users from using the device on driver unbind

From: Janusz Krzysztofik
Date: Thu Apr 18 2019 - 10:51:36 EST


Use drm_dev_unplug() to have device resources protected from user access
by DRM layer as soon as the driver is going to be unbound.

drm/i915: Use drm_dev_unplug()

Since this patch should be now safe for use if merged with current
drm-next or drm-tip branch which no longer suffer from incorrectly
resolved merge confilct that was breaking it, finally fixed by commit
bd53280ef042 ("drm/drv: Fix incorrect resolution of merge conflict"),
I'm resending it with Daniel's Reviewed-by: added.

Former patch 2/2 has been dropped as it is already in drm-intel-next as
commit 141f3767e7b8 ("drm/i915: Mark GEM wedged right after marking
device unplugged"). BTW, the wersion I sent was screwed up, not
reflecting Chris' intention precisely enough, but Chris was vigilant and
fixed it. Sorry Chris.

Thanks,
Janusz
