[PATCH -next] bus: fsl-mc: simplify DPMCP version check
Posted by Yue Zou 4 years, 3 months ago
The minimum supported DPMCP version is 3.0, and the second
half of version check is always false due to the limited range
of minor version's unsigned data type. Just remove the second
check to simplify the condition.
