Subject: drm/nouveau/kms/nv50-: fix file release memory leak
Git-commit: 0b3d4945cc7e7ea1acd52cb06dfa83bfe265b6d5
Patch-mainline: v5.15-rc5
References: jsc#PED-1166 jsc#PED-1168 jsc#PED-1170 jsc#PED-1218 jsc#PED-1220 jsc#PED-1222 jsc#PED-1223 jsc#PED-1225
When using single_open() for opening, single_release() should be
called, otherwise the 'op' allocated in single_open() will be leaked.
Fixes: 12885ecbfe62 ("drm/nouveau/kms/nvd9-: Add CRC support")
