Variable tmp is being assigned a value that is never read, the variable is redundant and can be removed.
Cleans up clang scan build warning: drivers/rapidio/rio-scan.c:561:10: warning: Although the value stored to 'tmp' is used in the enclosing expression, the value is never actually read from 'tmp' [deadcode.DeadStores]
