| Subject: IB/multicast: Check ib_find_pkey() return value |
| |
| From: Bart Van Assche <bart.vanassche@sandisk.com> |
| |
| commit d3a2418ee36a59bc02e9d454723f3175dcf4bfd9 upstream. |
| |
| This patch avoids that Coverity complains about not checking the |
| ib_find_pkey() return value. |
| |
| Fixes: commit 547af76521b3 ("IB/multicast: Report errors on multicast groups if P_key changes") |
