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]"
