[PATCH AUTOSEL 5.12 25/43] drm/gma500: Add the missed drm_gem_object_put() in psb_user_framebuffer_create()

[Sasha Levin]

From: Jing Xiangfeng <jingxiangfeng@xxxxxxxxxx>

[ Upstream commit cd8f318fbd266b127ffc93cc4c1eaf9a5196fafb ]

psb_user_framebuffer_create() misses to call drm_gem_object_put() in an
error path. Add the missed function call to fix it.
