+venus: destroy a device's object mutex after the objects that lock it
+
+From BattleTempest's DroidDeck-Pixel (kevinbryant551-ux/DroidDeck-Pixel, GPL-3.0),
+tools/venus/patches/0103-destroy-object-mutex-after-objects.patch. Bionic aborts on locking a
+destroyed mutex ("pthread_mutex_lock called on a destroyed mutex", seen on a Tab S9 FE G68
+and a Pixel 9a), so a client that exited holding objects took the render worker down.
