liuyuntao 38098444b7 virtio-gpu: fix possible memory allocation failure ... [ Upstream commit 5bd4f20de8 ] When kmem_cache_zalloc in virtio_gpu_get_vbuf fails, it will return an error code. But none of its callers checks this error code, and a core dump will take place. Considering many of its callers can't handle such error, I add a __GFP_NOFAIL flag when calling kmem_cache_zalloc to make sure it won't fail, and delete those unused error handlings. Fixes: dc5698e80c ("Add virtio gpu driver.")
