Subject: [PATCH 5.12 134/677] Revert "drm/qxl: do not run release if qxl failed to init"

From: Gerd Hoffmann <kraxel@...hat.com>

commit 93d8da8d7efbf690c0a9eaca798acc0c625245e6 upstream.

This reverts commit b91907a6241193465ca92e357adf16822242296d.

Patch is broken, it effectively makes qxl_drm_release() a nop
because on normal driver shutdown qxl_drm_release() is called
*after* drm_dev_unregister().
