| Subject: [PATCH] sdk_qbman: Fix error in IP revision comparison |
| |
| The comparison for QMAN_REV31 was incorrect as it |
| would always fail due to the wrong mask. |
| |
| This fixes the following error in newer GCC versions: |
| "error: bitwise comparison always evaluates to false |
| [-Werror=tautological-compare]" |
