Subject: [PATCH 5.9 187/757] drm/vgem: add missing platform_device_unregister() in vgem_init()

From: Qinglang Miao <miaoqinglang@...wei.com>

[ Upstream commit 57fb54082d5d14512dfd21bc39d91945d3ad1ee9 ]

When vgem_init() get into out_put, the unregister call of
vgem_device->platform is missing. So add it before return.
