| Subject: s390/kvm: Initialize uninitialized flags variable |
| |
| From: Claudio Imbrenda <imbrenda@linux.ibm.com> |
| |
| [ Upstream commit 64844729a608d308089510fc3bb23abf602f4e47 ] |
| |
| The flags variable was being used uninitialized. |
| Initialize it to 0 as expected. |
| |
| For some reason neither gcc nor clang reported a warning. |
| |
| Fixes: 05066cafa925 ("s390/mm/fault: Handle guest-related program interrupts in KVM") |
