From 3e1b9b2d81901b3ceeb5ec1f1b4c41cd1cff53ba Mon Sep 17 00:00:00 2001 From: Carl Vanderlip Date: Fri, 2 Jun 2023 15:04:39 -0600 Subject: accel/qaic: Free user handle on interrupted mutex After user handle is allocated, if mutex is interrupted, we do not free the user handle and return an error. Kref had been initialized, but not added to users list, so device teardown would also not call free_usr.
